Stop Stress in Its Tracks
Stressed out kitties can develop behavioral and health problems, leading to issues like marking, scratching, aggressive behavior and stress-induced illness. Composure helps calm cats using a unique combination of ingredients including colostrum, L-theanine and thiamine. Just give your cat the fast-acting, easy to administer soft chews or liquid formula at the first sign of stress behavior or during stressful situations.


For Everyday Stress
The advanced calming formula in Composure can be used daily to help nervous cats and those in new stressful situations adapt. It has no known side effects and won’t change your kitty’s personality or make her sleepy—just calmer and less stressed!
Fast-Acting with Customized Dosing
Composure starts working in as little as 20-30 minutes, so you can give it as soon as you notice signs of distress. You can even double or triple the dose for extra stressful situations without worrying about affecting your cat’s energy levels. Sudden thunderstorms, dinner parties and trips to the vet just got a whole lot easier!


Vet Formulated and Researched
The advanced formula combines extensively researched ingredients that work together to provide non-narcotic stress relief. Colostrum Calming Complex promotes stress reduction and improved cognition, L-Theanine supports relaxation and less irritability, while thiamine acts on the central nervous system to help instill calm.
Use as Much or As Little as Needed
Give Composure on a daily basis for general anxiety and nervousness or up the dose for particularly difficult situations or rough days. It’s a safe, non-pharmaceutical, herbal-free supplement, so it won’t cause drowsiness, personality changes or side effects even at double or triple the normal dose.

These definitely work!
By Michelle on Feb 22, 2021
Our ex-feral cat has been very stressed about our new cat. These treats have been a game-changer for him! He's almost back to his normal personality and is even standing up for himself against the new cat's attempts at bullying. I'm thrilled that we found these. We're only giving them to him once a day but that seems to be enough to build his confidence back.

works well, but hard for kittens to eat
By lizannstaff on Feb 24, 2021
These work really well, if I can get them into my kittens. They absolutely hate how hard these are. They're almost as hard as kibble but 4 times the size, so my 7 month old kittens won't eat these. I have to crumble them up and mix them into either a Churu treat or Tiki Stix treat. Once it's mixed into one of those two treats, they'll eat it no problem! Then 20 mins later, I have calm kitties!

Not Worth It For Super Crazy Cats
By kianacheyenne on Jan 13, 2021
Unlike most reviewers here, my cat did like them and did eat them, but it not help chill him out whatsoever. It might just be cause hes growing out of his kitten phase or something, but hes wild, and would go crazy at night, so I bought these thinking it would chill him out so I could sleep, but no. I tried it out for a month I would give him two before bed, and saw no change in his behavior. My kitten also got a uti shortly after I started giving him these, I dont know if it related, but it is worth mentioning. Definitely dont recommend this product. Also would like to note, I did take them out of the packing, and kept them in a closed container, but they still got "stale" quickly, and became Unlike most reviewers here, my cat did like them and did eat them, but it not help chill him out whatsoever.

Just another snack for my cat
By katy on Dec 28, 2020
My cat eats these with no problem, so I guess they taste good. However, I don't notice any calming effects. I got these specifically in hopes of calming him down during long car rides (whether it's to the vet or traveling during holidays). I was really hoping this would ease his anxieties but I didn't notice a difference, and he still cries majority of the ride. Also, I've been giving these to him when he's feeling particularly frisky (especially in the mornings when he meows at me for hours and throws himself around my room.) Unfortunately, these don't do the trick for him. My search for a calming supplement continues.

Iffy but mostly good
By Reptar on Feb 2, 2021
It’s hard to tell if they do much since my cat is so high anxiety right now (struggling with a recent onset of psychogenic alopecia) but they make enough of a difference I’ve repurchased once so far. I give one to her before I go to work and sometimes one before I go to bed depending on her behaviour.

Calming treats
By Mellow on Feb 23, 2021
They work! We took our baby (1.5 yr cat) on his first 4 hour trip and he ate the treats right away (no pill pockets needed) and slept. I could tell he was much more relaxed and did not cry at all during the trip up or back.

Maybe works for others, not us
By Joan on Jan 4, 2021
I read the reviews but this did not pass the "sniff test" for our cat. I probably should've known our cat wouldn't like them because he doesn't eat chewy treats, only crunchy ones, but I thought we would try them. Nope. He sniffed them and walked right away. I tried cutting them in half or even smashing them and putting them in food - no way! My boy, who normally gulps down food, would not touch it! So, now I have this bag of treats...can I return them?

As hard as a rock
By Kath on Feb 14, 2021
I was looking for soft chew calming treats and when I received these they were hard, but I thought maybe just frozen with cold weather. That was not the case they are very hard cat's won't eat them. I even put in water to try to soften up .

It's like crack for your cat
By wagsandpaws on Jan 4, 2021
These cat chews did the exact opposite of what I wanted; instead of calming my cat down, he got amped up. I had to lock the bag of cat chews in a cat resistant container because they would open up the cupboard and try to rip into the bag to get to the chews. So, if you want an expensive treat for your cat, buy these chews. Otherwise, save your money if you're looking for something to calm your kitty.

great item
By Elaine on Feb 28, 2021
My young cat sometimes has bouts of hysteria so I give him a couple of these chews and he calms down! He loves them and they are safe with no drugs.
