Dealing With an Aggressive Cat? 7 Reasons Why Cats Become Aggressive

Cats don't get aggressive out of nowhere. An aggressive cat is usually behaving that way for a good reason. Here are seven reasons why cats become aggressive — plus the warning signs and how to handle each.

JaneA Kelley  |  May 15th 2018

Even the most experienced cat caretakers can find themselves charged up on adrenalin when having to face a cat in the midst of a fit of aggression. But encountering a hissing, growling, screaming, and possibly even scratching and biting cat can strike terror into the hearts of people who don’t know how to handle an aggressive cat. But cats don’t just suddenly go crazy: There are almost always warning signs and there’s almost always a good reason for cat aggression. Here are seven reasons why cats become aggressive and how to handle an aggressive cat.

1. Cats Become Aggressive Because They’re in Pain

Cats who are in pain will respond with hisses and swats when sensitive areas are touched. My cat, Siouxsie, does this if I accidentally put pressure on her sore hips. A hard yank on the tail, for example, can be quite painful. Ignore the warning signs and a scratch and possibly even a bite may follow. This is especially true if the pain is a result of physical abuse such as being kicked or hit.

2. Fear Can Cause Cat Aggression

A terrified cat will respond with body language that’s obvious to an experienced cat caretaker: She will turn sideways and puff up her tail and fur in order to look larger. Her ears will flatten backwards, she will hiss and her pupils will dilate. Attempting to approach a cat in this state is risking an aggressive reaction, not because the cat dislikes you but because she’s in the middle of a panic reaction.

3. Hormones May Cause a Cat to Become Aggressive

A cat who is not spayed or neutered is much more likely to be aggressive. Male cats in particular are biologically wired to fight with other male cats when females in heat are present. If you see two cats fighting, do not physically intervene because you will almost certainly become the target of the cats’ aggression.

4. Cats Can Get Aggressive Due to Frustration

“Redirected aggression” is the term for violent acts carried out by cats because they can’t reach the object of their predatory passion. For example, an indoor cat who sees another cat walking by or marking his territory in “his” turf may get into a highly reactive state. At that point, anyone unfortunate enough to be nearby, whether that’s another cat, a dog or a person, may end up on the receiving end of the cat’s aggression.

5. Cat Aggression Happens Due to Stress

If a cat lives in a highly stressful environment — for example, a home in which people are fighting or a home with too many cats — it’s quite possible for that cat to be quick to respond aggressively. Like children who live in homes with a lot of verbal and physical violence, or a lot of unspoken anger, cats often act out the dynamics of their human families.

6. An Aggressive Cat Might Be Responding to Trauma

Don’t laugh: Cats can suffer from post-traumatic stress. Their brains are wired similarly to ours, and the effects of chronic anxiety from past human violence or struggling to survive on the streets can lead cats to become aggressive. In order to resolve this issue, a short course of anti-anxiety medication (prescribed by a vet, of course; don’t give your cat your antidepressants, please), homeopathic remedies or flower essences can help make a cat less reactive to triggers.

7. Chemical Imbalances Can Cause Cat Aggression

This is by far the rarest reason for cats to become aggressive. But like humans, some cats simply have biochemical imbalances that affect behavior. For these cats, antidepressants or anti-anxiety medications can be a lifesaver.

The bottom line on handling an aggressive cat

No matter what the cause of the aggression, there are almost always warning signs. If you understand feline body language, you’ll be able to see that your furry friend is getting wound up before the situation escalates to a crisis point. If you have a highly reactive cat and you want to help him or her, be aware that it will take time and patience — but take it from a person who has rehabilitated traumatized cats: The reward is so worth the effort!

      Hi. I have two kitties, both are almost 2 years old and spayed, and also strict house cats. They grew up together and always were the best of friends. But the older kitten (female) suddenly started growling at the other cat. She is very distant and doesn’t want any affection for the past 2 days. She is also not eating and behavior has definitely changed. What could be the cause of such a sudden change of behavior and aggression towards her fellow kitty? Please help…

      My cat attacks me while talking on my cell phone. Relentless and aggressive, not just cute playing and “i want attention.” I try to give him things to play with while I am on the phone but he lunges towards my arms, legs, back, wherever he can get his claws and teeth into. He digs in and gets more aggressive when trying to remove him. The second I get off the phone he returns to normal. I work from home so it’s really becoming an issue. I play with him, provide tons of attention, and he has lots of toys and windows to lay in. I need help! Why is he doing this?

      Hello!

      So I have this four month old cat and have had him for three months already. He has always been sweet and cuddly when I first got him but now he’s really aggressive and latches himself onto my legs or arms or anything thats skin! I’ve played with him for countless hours of the day and he has lots of toys and I’ve tried walking out or putting him in his room (with food and water and his bed and his toys) but he still persists. It got worse where he scratched my entire leg and dug his teeth into my leg leaving me bleeding, A LOT.. I don’t know what I should do, I’m not the kind of person to get angry or upset since I had fostered a female kitten before him and she was a sweetheart from the start and when she wanted to play she would bring me her toys instead of scratching or biting me. I have so many acars from him that people think I’m harming myself. What should I do? I’m going to continue to keep him and love him since I do haha but what should I do to imprive myself to be a better caretaker? Any feedback would be awesome, thanks!

      I need help. I have 3 cats- Lola who is 14 (not a factor in all of this as she is not affected at all) Neo 7, who is maine coon manx mix huge 18 lbs, and Leon 2 1/2 yrs tiny male orange tabby (maybe 7 lb).
      After living here in same home, peace with our yellow lab who is 100lbs Over the past YEAR Neo has decided to try and KILL little Leon orange tabby anytime they are in sight of one another. They are all indoor outdoor, fixed, etc. Ive seen this happen in our home and outside. After living with each other a year and a half???? He is so violent towards the little kitty who is submissive. The large cat goes so much further than swatting, its screaming like a horror movie and ultimately Neo pinning Leon in a corner often times by the neck biting and clawing him, hair goes everywhere. He is more than twice his size.
      Neo is a nice cat to me, my husband and generally likes people and even dogs. He exists with our old cat no issue at all. Last vet check they deemed him agressive-marked his chart to handle with care because he doesn’t react to his crate, car ride, vet well at all. I believe they called him a mountain lion, handle with extreme care. This happened this morning and I broke it up and Neo ran outside and Leon is hiding somewhere in the house, I don’t even know if he’s hurt as I can’t find him. I am so frustrated. I am living my life on pins and needles. I have no desire to get rid of any of my animals I love them all, I am just broken hearted. My husband thinks I am crazy acting like a doorman always scanning the room, yard to make sure they don’t have another round. Do cats go crazy? I could never be allowed to shove a pill down mean cats throat as he would eat me alive first and doesn’t really eat wet food regularly. Help me please ! suggestions!

      I have 2 cats one male and one female. I adopted them both from the same shelter 5 years ago. They have both been spayed and neutered and have always gotten along until now. My male cat got locked outside 3 nights ago but was let back in before daylight the same night. Ever since them my female has became hostile towards him. Any recommendations?

      We recently had kittens. We had to give a few of them away due to lack of room in our house. We recieved a call yesterday about the kitten (3 months old). The new owner asked if we would take her back because she and their dog were not getting along and was fearing for her safety. We picked her up this morning and as soon as we got her home she started growling, hissing, and biting everthing in her site. I dont know how to handle the aggression and how to help her. I fear her last owners dog hurt her or it traumatized her. Please help. I want to help this poor thing and cant afford to take her to the vet. We do have other animals (and her mother and a sibling still) including little dogs and fear for their safety.

      We adopted a male kitten from our local Humane Society when he was eight weeks old. Willie is now 11 weeks old, and nearly the entire time he has been a little monster about half the time. This particularly occurs when my wife and I are lying in bed trying to go to sleep. He will crawl up on top of the foot of the bed, crouch down low, and charge (usually) my wife. He bites her hand most often, but he has also bitten her face and even her breast during these attacks. The last couple of days we have been giving him kitty timeouts by putting him outside the bedroom and closing the door. We later find him curled up on the couch or blanket sound asleep. I don’t really know if this is the right thing to do with the little guy. I am recently retired and am home alone with him most of the day. I will have interactive play with him a couple of times a day but he still attacks my hands, wrists, ankles, and calves. I don’t hit his nose or anything, but I have sprinkled a few drops of water on him when he attacks me in the kitchen. How can we reduce this undesirable behavior in him? Furthermore, we are going to be adopting another male kitten and bringing him into our home in two days. The new kitten will be eight weeks old — about three weeks younger than Wild Willie. The reason for the second kitty is for Willy to have a buddy/quasi-sibling who can keep him company. We will be getting both kitties neutered later this year. Any advice would be helpful. Thanks.

      I need help. My cat is 18months old and he strikes out towards my children’s heads. It happens at least once a month from the time she was a kitten. He is not provoked he may not even be near the kids before he launches himself at their heads. My children have a been scratched and bitten near their eyes and I’m scared its going to be worse than a scratch next time. What do I do.

      I adopted a rescued stray cat about 3 years ago. She was nasty from the start. She was missing a front tooth which may have been from a fight or not. She is so fat but a 2 year diet did nothing. She lost 0 lbs. She has a very small head and tiny feet. When she comes to me she starts out licking me and cuddling but suddenly she turns on me and bites and scratches. I have never used any form of corporal punishment. I just remove myself from her presence. She is spayed. After all this time I would expect her to calm down knowing no one will hurt her. But, she seems unable to change.

      I have an agressive cat in my grandparents house. She was a stray and She followed my grandad home because he would regularly feed her and other cats. She ended up settling in his house (at the time She was about 6 months old now she’s 3 years) I never knew why she became agressive because She was always around me and always wanted to be pet. Now she just sits alone at the Window and growls when we come near and when she’s with me she’s calm unless i touch her or move my legs. If i do that She hisses and runs away. I don’t know why did i do something wrong? Did she get sick of me? It kinda breaks my heart because she was really close i don’t even dare get close to her now because Im too scared

      PS It’s also going to be difficult to find her a new home. I am not a cat person, and this cat is terrified of cat carriers. My dad didn’t have her vaccinations current for a while because it was so difficult to get her in them.

      After being hissed at for about week every time I come to feed her, however, I am really starting to hate her. If she were crying and coming to me for support, I’d feel differently. I’m not without a heart. But after feeding her daily for over 2.5 months, she’s suddenly going to see me as a threat and need to hiss at me because I am feeding her?

      My and my mom’s lives has been turned inside out because my dad did not take care of anything to prepare for his death. He took care of everything before he died (my mom didn’t even have a credit card in her name because she has health problems that make her a complete dependent), and so we have had to deal with all sorts of nonsense in addition to a ton of medical bills, closed financial accounts, probate court. I really don’t need this cat giving me grief right now.

      I have a street cat who is a total bully and is always picking fights with the others that frequent the same areas. History: I rescued Buddy when I found him with a huge gaping infected fighting wound between his shoulder blades. After neutering and multiple surgeries to heal the wound and 2+months recovering in my spare bathroom, I reintroduced him back to the garden. At first all was ok, and then after about 6-8 months he started throwing his weight around a lot more and bullying and injuring the other garden cats (also neutered). I’ve never seen a neutered male behave so aggressively all the time. I’m getting beyond frustrated for the other cats. It’s very sad to see them with sometimes serious wounds from him. Furthermore he is extremely vocal and loud. It’s a real nuisance for the community. I’ve tried spraying him with water but it hardly phases him.
      I’m seriously considering euthanasia because it’s unfair to the other cats to suffer so much from his bullying and injury.
      What are your thoughts about de-vocalization surgery? My thoughts are that it may take away his ability to vocally bully which leads to escalation and then fighting. So it may ‘clip his wings’ so-to-speak and lower his confidence and put him level at least in the higherarchy among the other cats. But my fear is that he may become more frustrated as a result and I don’t know how that might manifest…thoughts?

      Hi All,

      Hoping for some advice. We have had our cat for nearly six years now (since she was a kitten) and we’ve been dealing with her aggression for about five of these years. It initially started with just a few people, but now it is to the point where we cannot even have her out when anyone is over because she will be on edge and show all the signs of an attack – low ears, growling, heavy tail whips, etc. She has physically scarred both my husband and I. She was fine with our other cat – they cuddled, washed each other everything – and then another cat started coming to the window and this literally set off a series of events that resulted in us having to rehome our other cat. We’ve tried calming food, diffusers, we’ve talked to the cat behaviourist in our city who suggested play time. We are so incredibly busy, but I do try to play with her interactively at leave for 15 minutes a day plus we have battery operated and other toys for her. Now that it is summer it seems like every neighbourhood noise, every bug, every everything is causing her to be wide-eyed, flat eared – just on edge. What can I do? I’ve considered trying CBD oil as our last measure, otherwise with we broken hearts it seems like the only other option is to have her put down. Our area’s no kill shelters are at cat capacity and will not take anymore (not that we would put her in such a stressful situation). I am just at a loss. Any advice or help would be so appreciated.

      Thank-you.

      I have a cat who is about four years old. We got her as l kitten of a couple of months old from someone who couldn’t keep her anymore. She has always been very temperamental and although she has become slightly better, she still attacks my scratching or biting hard. There don’t appear to be any pattern but sometimes if you stroke her she will appear to be enjoying it but then wham… she sinks her teeth into you. Any advice?

      For Mitchell Stein
      I am a cognitive ethologist. ….Animal Behaviorist……please please don’t have this cat put down……it sounds like you are dealing with redirected aggression issues here…….many times we as humans don’t understand the motivations of another species and when they react in a way that is natural for them we label them bad or judge them….
      If you can’t deal with the situation…..and many times it is hard to understand. ….please please contact a no kill rescue…….most will take him for a small donation. ……and years from now you won’t have to feel badly…….this is not meant to judge you only to help your cats and you and to keep an innocent creature from dying unnecessarily…….please reconsider……

      I have lived with cats for about 60 years and have never encountered an aggressive one. And this includes cats I have rescued from the wild, cats that the vet said would never make good pets but all turned out to be sweet and loving. This could be because of my approach – I never tried to force anything on a cat, and let them adjust on their own schedule, and provided them with a safe space along with food bowl that was always full of raw liver typically. And BTW, the fact that I always had tasty treats probably helped.

      this may sound “old hat”, but go to YouTube and search both Jackson Galaxy, and My Cat from Hell. he may look a bit odd, but he has proven, sound advice. five minutes of playtime twice per day with your cat should release a lot of frustration and bottled up energy. our Baxter was a rescue, who just showed up at the Cat Hospital, his head covered with blood. he is now a comfortable 100% indoor kitty, but still gets seriously upset if there’s a cat on “his” front porch.

      Reading these comments, I would have to suggest 1)always neuter your animal, 2)keep nails trimmed, 3)leave an emotional cat ALONE! Don’t “console”. Don’t reward bad behavior. Turn your back on all biting or you will encourage the behavior. Use spritz bottle to interrupt bad behavior between cats. They will get it quickly and scatter.

      A vet once told me I would have to re-introduce a cat that was quarantined for 2 weeks and he was right even though the cat had already been introduced once before – successfully – into the household. I am still having to keep him in the bathroom, separated by a screen door, when I am gone, to ensure he isn’t scared by another cat that periodically gets into skirmishes with the others, including the dog. When I am home, he is able to roam freely. Probably too many cats right now for the space. The aggressive cat is younger than the others. She is strong and edgy. They tell me this isn’t unusual for white females. I use the water spritzer for behavior I don’t like and affection for behavior I do. She is learning.

      Another thing to try when cats are being aggressive toward their humans is the pheromone diffusers or collars. This helps many cats and can also help with spraying or marking, even for neutered males who continue that behavior. I’ve actually had good luck with the flower essences, but like anything, be sure to get a reputable and known brand.

      You left out a dynamic I have seen several times. I always have 3 or 4 cats and I have plenty of room for all of them. They are all fixed. There is always one who is the alpha, getting the best perches and sitting in my lap first. When the alpha gets old and sick the other cats will go after them and try to fight. You don’t think of house cats as a pack but they are. Just like lions. I asked my vet and she said her cats do the same thing.

Friday he was fine all day Saturday he was fine until 11 pm when he attacked my female cat again. Now it’s Sunday and he again attacked my female. Both are and have been fixed from the time they were young and updated on shots. My female is 8 and he is 5, nothing in our household has changed either. I am on the verge of having him put down, I can’t deal and won’t deal with his attacking my female.

        Sorry to hear that you’re dealing with this. Please reach out to your vet or a professional cat behaviorist. Worst case scenario, if you really cannot make it work out, please give your cat to a no-kill rescue shelter instead of putting him down.

      My 2yr old ginger female fixates on birds (thru the window) in the eaves of my house. If I disturb her, not on purpose, she’ll ‘haw!!’ at me, hiss, and swipe at or try to bite me. I leave her be and come back later to make my bed-where this activity takes place. Perhaps she interprets my actions as trying to get HER birds.

      This is for Brittany. For some reason, I can’t directly respond to your post. It sounds like she may have been expressing redirected aggression. Sometimes, things unbeknowstvto us, disturb a cat and the cat, will suddenly attack whoever or whatever is near by. My cat does this when she hears certain noises, for instance when I yell out if I stub my toe or hit my funny bone. She comes flying out of nowhere and bites me. Once she pierced my thigh with her teeth and I had 4 bite wounds. She used to attack another of my cats and bite her on the neck, but this other cat was so calm and tolerate, she never seemed bothered by the other cat {admittedly, it seemed like a Love bite] After this sweet cat died, we got a new older cat who does not tolerate the other cat and they get into some bad fights .

      This happened over a month ago and was out of my control, but my family forced me to put down my non spayed 2 year old female cat after she attacked me 3 times. The first attack happened because my cousin jumped on me while I was sleeping, startling me, and my very anxious sleeping cat. She lashed out at us, jumped on us with her claws out and slashed us repeatedly. She was hissing and even spitting. Talk about a rude awakening!! Her spit was all over my pillows and headboard, not to mention my blood being all over my sheets. She cut me pretty deep in a couple spots on my legs, and I had a very deep cut on my wrist that I got from blocking my face. I tried to console her afterwards, and she began hissing at me and charging me… She was my first cat so my family was unsure of what to do. We called animal control and were forced to put her in hospital quarantine. After the quarantine, she seemed to be back to normal, so I brought her back home. The day after, I was crying in my room due to an unrelated issue. I guess it was my heavy/erratic breathing that set her off, but she attacked me again! In the same fashion as the last attack: Very aggressive, claws out, repeatedly slashing me. My legs got torn up pretty badly, and I was so terrified of her… We were able to trap her in a small cage we had, and she looked up at me wide-eyed and meowing as if nothing had happened. After that second attack, my family didn’t trust her and neither did I, honestly. They made me take her to get put down. I’m so torn up about this because I loved her so much, and she was so beautiful. I just have no idea why she turned on me so suddenly… Anyone have any idea? She’d always been on the edge and anxious, so I’m guessing maybe she had a hormonal imbalance. Thats what our vet told us, anyway… Someone give me some feedback please!

      Hello. I have been incredibly worried about my cat for about a month now. We often refer to him as a “lover boy” because he’s most likely the sweetest cat you will ever meet. We named him Shadow because he follows me around like a dog (no, seriously, he follows me everywhere), he comes when you call him, he lets you pet him everywhere (even on his belly and paws!), he loves to snuggle, and he cries when he can’t see me (if I leave the room, if I close a door, etc). But for about a month now he’s been aggressive – but only under certain conditions. If I sit next to him on the floor with my legs crossed, he starts crying. His crying quickly turns into more of a warning; it gets higher, louder, and more threatening. He then proceeds to try to bite me anywhere he can: my arms, legs, even my sides. The bites never draw blood, however they do leave indentation marks that are quite alarming. It’s almost like he’s possessed. He tries to crawl into my lap (to get closer so he can bite me) and lightly scratches at my legs as he does so. He used to do it only in my room, but now he’ll do it in the living room when my parents aren’t looking. That’s another weird part about it: he only does it when we’re alone. He’ll immediately stop when my parents walk in my room. He only does this to me. Right now he’s sitting next to me and I’m petting him as if nothing happened five minutes ago. He does kind of bully our other cat, so maybe it’s redirected aggression because we often prevent him from bothering her? Please help.

      My 3 year old female spayed cat has suddenly started being aggressive. My girlfriend of 3 years came over, wore a pair of moccasins that my cat had never seen before. The cat freaked out, ran into the bedroom. When we followed her, she poofed up, hissed and growled. She has never done this before. She repeated the behaviour today when I was putting on my socks.

      My female cat not spayed is loving and sweet and sleeps with me all the time. But anytime anyone comes over she will run up on them and then start hissing. She has swatted at others and after they leave she want to be loveable again but it is progressing to growling and hissing and lunging at me. Seems like anxiety as she does this to everyone but me. No one is hurting her and they try to sit still till she gets used to their smell but nothing works. She ends up hiding till everyone is gone but has started to do the same to me. I say it’s anxiety that she doesn’t know how to release but I have no idea how to help her calm down and not be anxious or too excited. Is this just possible since she has not been spayed?

      My orange cat hates my guts half the time. Literally half the time. Some times I can hold him and pet him. Other times if I even try he attacks me. Like I’m bleeding right now cause if him being like this. There are also times he just starts peeing on me when I won’t let him go. I was trimming his nails and he tried yo get away and I wouldn’t let him go so he starts to growl and pee right in my lap. I go to pet him and sometimes he perks his head up to reach my hand, other times I get an inch from him and he hisses at me and runs away. I don’t know what to do. I’m tired of bleeding. I’ve taken him to the vet and described this issue to the vet and the vet said it’s normal. I need advice. There are no unfixed female cats around. He isn’t fixed but that’s my next move. Anything else I can do?

      My 5year old male neutered cat has an occasioal aggression problem. He is usually very loving, sits in my lap and follows me around. He lets me kiss him and will turn his head up for me to do so. ( Sorry people, yes, I’m a cat kisser)! But, once in a while, he gets that look in his eye, stares at me intensly and then strikes out, biting me on the arm or leg. He does this so fast that you can’t really see him. He bites, releases and sits back as if to say, “there, I showed you”. He draws blood and leaves a tiny three cornered bite.
      I wish I knew why he does this and what I can do about it. I also have an older female whom he sometimes chases. They tolerate each other, usually.

        My 4 year old female cat does the same thing. She can be very affectionate towards me, and then out of nowhere she attacks me. It’s now happening more frequently, about every 2-3 weeks. If I’m sitting, perhaps looking at TV, I can catch her staring at me. If her eyes are dilated I throw a paper ball or something to distract her. If I don’t notice her, you can be sure that I will be attacked. My husband and daughter are shocked because I’m the one that feeds her and cuddles her. Her bites usually break the skin and sometimes the area swells and is sore. I don’t know what to do. I love my cat but I’m also fearful of her.

        Neutered or not, male cats want to be the “Alpha” unless you have claimed the role. Nips/biting is one “I’M in charge” warning.
        Like yours, my cat was loving, lap happy, and would do so without warning, but his most long lasting, frightening attack came when I tried to bring a cage-trapped feral into the home. After that, even if my cat saw me lingering with the feral outside for a few moments, I’be in danger of some nasty scratch/bites when I came in.
        That “Dog-Whisperer” has many methods of claiming the Alpha role but none worked on my feline housemate.
        I seemed to have 2 choices… Bring him to Animal Rescue or beat the crap out of him. His “Normal” attitude was so great that I was very reluctant to do the former, and too animal loving to do the latter.
        After his 3rd, attack, I gave him a STRONG reminder of where his “suppers” came from. Mid-day I scooped up his dry food bowl ‘s contents and dumped them out, and did NOT put down his usual mid-day wet food “Supper.”by bedtime, he was already becoming super mellow and cuddly. Three words he recognizes are… “No” and Supper” and “Bad. ”
        Combining the three words and… his name repeatedly, seemed to awaken a new awareness to him.
        By morning, it was hard to ignore his plaintiff meowings, but I had promised myself to hold out for at least 24 hours.
        About 26 hours in, I caved, and brought out his fav wet food, but held it out of reach somewhat as I quietly and calmly verbally reminded him of his badness. Any time after, if he even lightly bit, I’d walk over to the eating area while he watched and removed any food. Half a day was then enough. Mellowness ruled. ( For awhile.) BUT… Eventually he relinquished the Alpha title!
        P.S. Any time I was outside to feed the feral, I took to putting indoor kitty into another room where he couldn’t watch, and if I had petted the outsider. I made sure to wash my hands of any feral scent on coming back in.

        Could it be when your kitty stares at you, you are starring back with your eyes wide open?Try to slowly shut your eyes instead, a few times. Cats feel threatened when you stare at them with eyes wide open, better to have them slightly closed.

      Catster, Catster, Catster, what are we going to do with you. You forgot one very important potential reason. She could be hungry. It is so sad and pathetic we humans dictate to these beautiful creatures when WE think THEY should eat, we dictate the times to THEM, and specifically, put the absolute horrifying stuff of nightmare legend crud garbage known and sold as commercial waste, I mean cat “food” in their faces, yet many wonder why they walk away, get agitated, don’t behave “properly”, get sick, and receive their untimely, wholly, and grossly hurrendous early euthanasia. AAFCO needs to get their head out their ass, step their game up, and look up to the standards set forth in Europe, where they have literally eliminated Feline Cancer, if they even give about quality control and allowable ingredients, they could take credit for reducing and removing kidney failure, hyperthyroidism, and all these other unthinkable diseases and early untimely deaths we are literally feeding my babies. But not me, I’m ahead of the curve. Omega 3 Icelandic wild caught fish oil, free range meats, quality dried, and water, water, water. Cats like to eat relatively frequently throughout the course of a single day. My 17 year old probably likes to have roughly 10 stomach fill ups in a day, in between her roughly 10 naps, and among her roughly 10 visits to either of her 2 running water fountains. I feed her real actual meat and protein frequently, NEVER E.V.E.R. complete crud garbage like Friskies, and almost never Fancy Feast, I go with Soulistic wet canned, Orijen dried, real catnip in the garden, ice in her water, and for being the oldest cat in the neighborhood, she’ll probably outlast them all too. My ideology, more food, more nutrients, more beneficial digestion, enzymes, greater immunity, more tools for her body to work with to fight disease and aging, and increasing her physical and cognitive ability. Doesn’t hurt she has two pet steps, and her own cozy getaway in the form of a tent on a couch. You may refer to me as The Egyptian. Thanks for reading.

        So nice to hear someone so tuned into kitty. My boy is also on special diet, always has clean water. One cat and spoiled rotten, but does not get store food.

      Your older cat, who had the surgery, maybe she is having pain still? If she is in pain she might feel vulnerable. I agree with the others who say get another vet! Then look into the pain issue.

      Good luck, I hope your girls can be friends again.

      I am having a hard time posting this for some reason.I think the aggressor feels very vulnerable.Seperate high perches might help.I have played with my seven all at the same time with a laser and they forgot about the aggression and even the shy one got involved,also rewarded them with treats.I agree about a new vet also.He may still be hurting.He needs reassurance and you should see if something else hurts.

      just a shot here but maybe tuna oil on the non aggressor?keep them separated but initially offer some tuna to both within eyesight of each other.put tuna oil on the non aggressor often enough for the aggressive cat to smell it and associate the non aggressor with that scent.you don’t have to actually feed them some tuna every time you just want to make a pleasant association.Give the aggressor alot of space from the other cat.Sounds like he feels vulnerable.Maybe separate high perches.The aggressor needs alot of reassurance and patience.Even playing with them together can distract from the insecurity with a laser pointer or something that involves you all and then reward with treats.That helped us.Good luck.

      I have 2 spayed females, 6 & 7 who were best friends until the 7 yr old had surgery for bladder stones in April. She will attack my 6 yr old at every opportunity. The 6 yr old has ptsd! I have to keep them separated now. We tried pheromones & an antidepressant, but nothing helped. Now I have them eating in sight of each other separated by the babygate. Would love more info. My vet said to put her down but I can’t. Thanks

        Run don’t walk to a different vet. Any professional who would say that cannot be trusted with your fur babies’ care. With that said, I feel your pain and hope your girls work it out.
