    1. Rescue Remedy Stress Relief Pet Supplement – Best Overall

    Bach RESCUE REMEDY PET Dropper

    We think that you will love Rescue Remedy Stress Relief Pet Supplement for your cats. It’s our personal favorite overall because it is natural and effective—plus, it’s vet recommended.

    There are five flower combinations, called bach flowers, used in the recipe to calm your stressed cat: the star of Bethlehem, rock rose, cherry plum, impatiens, and clematis. Each one has been linked to soothing properties that can help your cat.

    These drops are taken orally but should not be given directly into their mouth. You just add four drops to water or food and offer it to your kitty. And it also doesn’t end with your cat. You can give this to virtually any household pet, and it’s safe. Depending on the severity of your cat’s anxiety, it may not work for all felines.

    Pros
    • Vet recommended
    • Natural
    • Easy to administer
    Cons
    • Might not work for all cats

    2. Nutramax Solliquin Calming Cat Soft Chews

    Nutramax Solliquin Calming Behavioral Health Supplement

    Nutramax Solliquin Calming Cat Soft Chews are a great option for their calming effect and the fact that they come in a 75-count bag. This bag can last over two months for an average-sized cat. These chews contain l-theanine, magnolia, and Phellodendron extract to promote ultimate stress relief, so always make sure to check the label or ask your vet before administration to make sure they’re the best choice for your feline.

    Unlike some other stress relievers, these chews promote sleep—so it does affect their overall schedule. They’re safe enough for daily use and should ideally be used in combination with behavior modification in consultation with your veterinarian.

    These chews are meant to work with an actual behavioral plan to treat anxiety with your vet’s help. They take up to 45 days for ultimate effectiveness, so you shouldn’t give these chews to your cat expecting to see immediate results.

    Cons
    • Not for immediate relief

    These chews also have a calming complex added in the form of colostrum. Colostrum has natural properties to calm your cat without changing their personality, making it ideal for everyday stress.

    Buyer’s Guide: Select the Best Calming Supplements for Cats

    All cats have different personalities and will respond to situations in their own way. If anxiety is a problem, it can present itself as a chronic condition or just a situational reaction. Regardless of the reason, you will want to book an appointment with your vet if you suspect your cat is suffering from any form of anxiety or stress to reduce its effects as best as you can.

    Here we will discuss possible causes of stress and anxiety so you can determine where your cat falls on the scale and the best course of action to take.

    Situational Anxiety in Cats

    Some kitties may be fine on an ordinary day until something tips the balance of things around the house. The good news is, environmental factors are sometimes the easiest to treat because you can accommodate your cat to make them most comfortable.

    Many times, you can pinpoint the root cause of anxiety or stress. A majority of the time, it spikes from noticeable changes that you are well aware of.

    • Loud Noises

    Your cat may be particularly sensitive to loud noises, which can be perfectly normal. Your cat may dart under the bed when they hear a thunderstorm, fireworks, alarms, or other obnoxious noises that they can’t place.

    • New Home Changes

    Cats are often creatures of habit. They might get bent out of shape if you move to a new home or even bring home a new appliance or piece of furniture. These changes are temporary and your cat can certainly adapt, but they might need a little help while they’re in transition.

    • Vet Visits

    Let’s face it—vet visits are rightfully scary for a lot of pets. It’s full of unfamiliar animals, smells, and people. Plus, your cat may correlate the vet with bad experiences involving surgery, shots, and other not-so-good memories. It’s natural for them to be apprehensive about the whole situation.

    • Grooming Trips

    Not all cats like being handled by strangers. Cats can be very particular about who they allow to pet them, let alone comb, cut, and bathe them. Like the vet’s office, seeing all the new stimuli can also take a toll on them because everything is totally unfamiliar.

    • Travel

    Many cats don’t care for car trips. Not only is there movement happening that is a weird sensation—they also might not like being crated or trapped while it’s happening. Though perfectly understandable, giving your cat a supplement during car trips can help to take the edge off.

    • Family Additions

    If you bring home a new baby or add new members to your household, it could definitely take a toll on your cat. They won’t understand much at first—they only know their safe space is being invaded by new people, which can be an emotional time for them.

    • New Pets

    It’s not unusual at all for your cat to be totally unsure about a new pet in the house. Whether it’s a hyper new puppy, an invasive new kitten, or another unfamiliar critter, your cat may not be happy at all that you brought them home. To help your pet adjust, supplements can be very beneficial to them.

    Anxiety Caused by Past Events

    Sometimes, anxiety and stress aren’t environmental at all. There is a chance your cat can have anxiety that stems from preexisting abuse or neglect. If you have a cat who has had a less than favorable past, it’s only expected that some residual emotion can follow them. To calm them down, you might have to put them on a long-term behavioral transition plan with the help of your vet.

    Many over-the-counter supplements can help to take the edge off of your cat, so they aren’t so excited all the time. The ability to relax and feel safe in their environment is something every animal should have, no matter what you have to put in place to accommodate them.

    Signs of Anxiety

    Cats can exhibit a wide spectrum of behaviors that point to anxiety. Some might be extremely apparent, while others may stay under the radar for a while. You might think your cat just has certain quirks or traits that make them act the way they do without realizing the underlying factors at hand.

    Some cues of anxiety are:
    • Toileting outside their litter box
    • Frequently meowing
    • Acting skittish or apprehensive
    • Hiding from any sudden movements, noise, or people
    • Overgrooming, which may or may not involve hair loss
    • Decreased appetite
    • Destructive tendencies like clawing or shredding belongings

    While these behaviors can no-doubt be a challenge for owners, it’s up to you to implement a plan to reduce the struggle for your cat. If they have any of these unwanted behaviors, the likelihood of an underlying issue is almost definite.

    Consult with your veterinarian so you can select the right plan for your cat. If you proactively handle this situation, you can ease the symptoms and reduce anxiety—and everyone in the home will be a lot happier when you do.

    Finding Helpful Supplements

    Once you have a plan in place, you’ll want to get ideal supplements that serve the needs of your cat. There are lots of options on the market, and you’ll probably not have much of an issue with selection. Circle back to our reviews if you’re having trouble landing on the right one for your kitty.

    Long-Term Treatment

    Some medicines are designed for long-term use, meaning that they don’t always work immediately. They have to get into their system and slowly kick in over the course of several weeks before they reach ultimate effectiveness. These treatments are best for cats who have continual anxiety.

    Short-Term Treatment

    Other supplements are designed to work right away. About a half-hour after you give them the treatment, you’ll start to notice a reduction in anxious behavior. These methods work better with cats who get flustered about outside influences—and not so much an overall sense of anxiety.

    Different Forms of Administration

    Cats will have varying tastes and preferences. Some cats won’t resist medication, while others will fight you tooth and nail. That’s why the market has so many options for cat owners to pick from.

    The most common types of formulas are:

    Some may work better than others, and some are easier to give to your cat. It will totally depend on the individual feline.

    Active Ingredients in Supplements

    You can also make a decision based on natural ingredients versus synthetic ingredients. Ultimately, it will depend on your cat’s sensitivities and the severity of the anxious behavior.

    Effective Ingredients
    • Herbs—plants like chamomile, clematis, and cherry plum are shown to improve anxiety
    • Melatonin—this naturally produced chemical promotes healthy sleep and relaxation
    • Colostrum—found in mother’s milk, this substance has soothing effects
    • L-theanine—this is a sleep aid and relaxing agent
    • Alpha-casozepine—naturally occurring in cow’s milk, this has calming properties
