Care Tips for a Healthy Cat Butt

Taking a good look at your cat’s rear should be part of their grooming routine. It doesn’t have to be complicated: You can get into the habit of observing your cat’s anus during brushing sessions and by monitoring their pooping habits.

If your cat has very long hair, you or a groomer can gently trim the fur around the anus to make it easier for you to observe any potential issues. This will also make it simpler to clean if there is dried poop and other debris in the area. If your cat frequently has a dirty anus or otherwise doesn’t seem to be cleaning themselves, contact your vet.

Cleaning your cat's sensitive areas can be tricky, but high-quality wet wipes can make it much easier. Try a natural, hypoallergenic option like Hepper's Wash Wipes, made with moisturizing ingredients and specifically designed to gently clean your cat's skin and fur. These wipes are as convenient as they are effective!

At Catster, we’ve admired Hepper for many years and decided to take a controlling ownership interest so that we could benefit from the outstanding designs of this cool cat company!

Why Are Cat Butts Important to Cat’s Health?

A cat’s rear end can be a goldmine of information if you know what to look for. A cat’s anus is not only used for normal digestive functions, but it also allows the cat to communicate with their fellow felines and mark their territory.

In fact, the anal glands, located on either side of the anus, play a vital role in communication. These glands produce a unique odor that is released when the cat rubs against objects. This odor is unique to each feline, which is particularly useful for stray cats, as it enables them to mark their territory and communicate with other felines.

Furthermore, a cat’s butt can be indicative of underlying problems. For example, the anal glands can become infected or inflamed, which will lead to discomfort and pain. By carefully observing your cat’s anus, you should be able to see if there is fecal residue, abnormal and smelly discharge, blood, or even intestinal parasites, such as tapeworms.

What Are the Different Types of Cat Butt Issues?

A few things can go wrong with cat butts, especially with the anal glands.

1. Impaction

In a healthy cat, the anal glands normally empty during bowel movements. However, if the anal sac canal becomes inflamed, fluids cannot be drained properly. In this situation, the anal glands may become impacted (i.e., plugged), and the fluid that accumulates inside becomes thicker and darker.

Several signs may indicate that your cat's anal glands are impacted:
  • Your cat is constantly licking their anal area.
  • Your cat has difficulty sitting properly.
  • Your cat is reluctant to go to the litter box.
  • Your cat meows during defecation.
  • There are bald spots or knots of hair around the anus.

2. Infection

If left untreated, anal gland impaction can progress to an infection in your cat. Indeed, when the normal drainage of the anal glands is disrupted, the bacteria present in the area take the opportunity to multiply, which can lead to the formation of an abscess due to the accumulation of pus.

The signs of an anal gland infection are much the same as those of an impaction. There may also be redness and swelling around your cat’s anus. In any case, it is necessary to consult your veterinarian as quickly as possible, so they can treat the infection by expressing the infected gland. If necessary, the veterinarian may need to puncture the abscess to facilitate drainage.


3. Presence of a Smelly Fluid

Cats use their anal glands to communicate with their feline companions, but they also function as a response to fear or stress. So, if you notice a foul-smelling beige or brown fluid around your cat’s anus, they probably just expressed their anal glands.

However, smelly fluid leaks can also occur if the anal glands rupture. Other potential causes of smelly fluid include diarrhea and pus resulting from infections.

4. Anal Bleeding

Anal bleeding in cats can be worrying. It can result from ruptured anal glands or diarrhea and from other things like parasites or internal trauma. If your cat is experiencing severe anal bleeding and it is accompanied by severe vomiting or diarrhea, lethargy, weakness, and pale gums, you must seek veterinary attention urgently.


5. Parasites

Small rice-like segments near the anus could be a sign of tapeworms. These tiny bits of white or yellowish tapeworms may also be visible in your cat’s fur, in their litter box, or on their bedding. Fortunately, most parasitic infestations can be easily treated with appropriate deworming medications prescribed by your veterinarian.


6. Weight Issue

Overweight cats may have difficulty grooming themselves properly, which is why their rear ends aren’t spotless. A well-kept and clean normal cat anus is a positive sign.

7. Arthritis

Just like overweight cats, cats with arthritis may have their mobility affected, meaning they will have difficulty grooming their butt meticulously.


8. Rectal Prolapse

The rectum is the part of the intestinal tract that connects the large intestine to the anus. Rectal prolapse occurs when part or all of the rectal tissue protrudes beyond your cat’s anus. This is a serious and painful condition that must be treated as quickly as possible.

Rectal prolapse can be caused by intestinal parasites, constipation, or diarrhea, most commonly. Signs include swelling, redness, and inflammation around the anus.

If your cat shows signs of the symptoms above or you suspect they might be suffering from underlying health issues, you should contact your vet.

Frequently Asked Questions

Why Does My Cat Drag Their Bottom on the Floor?

If your cat is dragging their butt on the floor, or “scooting,” it might mean they have an issue with their anal glands, so it’s best to see your vet for the right diagnosis and treatment. Scooting can also happen when your cat’s rear end is itchy. There are various reasons, such as parasites, allergies, or simply fecal matter being stuck in the fur around their anus.

How Can I Prevent Tapeworms in My Cat?

Regular deworming, flea control, and keeping your cat indoors can help prevent tapeworm infestations.

What Should I Do If I Notice Redness or Swelling Around My Cat’s Anus?

Seek prompt veterinary attention, as it could be a sign of rectal prolapse, infection, or other anal gland issues that require medical care.

Conclusion

Checking your cat’s butt may sound like funny advice, but your cat’s anus can actually reveal vital information about their health. Indeed, a cat’s behind can be a good indicator of underlying health issues, mostly related to their anal glands, but it can also indicate parasite infestations, digestive issues, or even a weight problem. Therefore, next time that you take your cat to the vet, ask them to take a good look at your cat’s butt, so you can have better peace of mind knowing that your cat’s behind is as healthy as it can be.

  1. My cat is 19years old his sent glans after he use the letter box I make sure I clean his paws because he always wants to sit on my lap so I make sure everything is dry. My question is his sent glans have black things that stick out so when I clean his butt they just come off,is this something that comes with getting old or should I keep an eye on it

    1. Hi Lizbeth. It is quite common for a 19-year-old cat to develop "black things" around the anal area, which are typically impacted secretions from the scent glands (anal sacs) or even harmless lentigo (age spots) that can accumulate waxy debris. As cats reach their late teens, they often lose the flexibility to groom themselves effectively, and their skin produces thicker oils, leading to these small, dried "plugs" of scent material that simply flake off when you clean them. However, the risk with an 18 or 19-year-old cat is that these glands can become truly impacted or infected, which causes pain, swelling, or a foul odor; if you notice him scooting, excessive licking, or if the area looks red and inflamed, it could indicate a more serious issue that requires a vet to manually express the glands.
