About VetriScience Laboratories Cat Food

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.

Truly Calms Cats!

I understand the mixed reviews. I believe the issue is that some cats simply do not like the consistency of the chew (its more hard than soft)however, this WORKS! What I do for my very nervous feline, is cut the chew up in three pieces and give to him. During any stressful time I usually give him two at a time. Within 20 minutes he is much more relaxed and calm. I don't think it is fair for some of the reviewers to give low rates based on whether their cat will take it -- the rating should be based on if it works, and IT DOES. :) I truly appreciate Chewy and the wonderful service and Customer Service folks -- they are always such a joy to speak to. Thank you Chewy, for all your wonderful products.

It works!

I can't recall why our vet recommended this but something I told her made her think our cat might be stressed. He just wasn't very affectionate and didn't like to stay on our laps. This truly changed him! He's so much sweeter and will sit in our laps for long stretches. We'll definitely keep using this and plan to try the dog version for our pup who gets anxious. And our cat LOVES to eat these. But in all fairness, he's the most food motivated cat I've met! So he's not the best judge of the taste, ha.

They work!

I bought these for my insane siamese boy to help him relax. The first one I gave him made him melt into his cat tree and just stare at the wall. He loves the taste and eats them right up every time. The effectiveness of the chews depends on how hard his demons are working that day - sometimes he's super chill, other times he needs 2 a day. They do definitely help him interact better with the other animals in the house and not get overwhelmed easily.

HARD chews, like rocks

Chewy was very helpful and sent me replacement bags, but unfortunately, they were all from the same batch number. These chews are so hard my cat cannot eat them. He really tries but it looks like it hurts him to eat them. I'm going to try to crush the chews with my mortar and pestle. Then I'll sprinkle them on his food to find out if they even work.

Calming supplement

I’m not sure how my cat grew up in her previous home, but she constantly meows. She goes to the vet regularly and she’s perfectly healthy. She just likes to be vocal lol. Whenever it’s time for bed, she always sleeps right up beside me and will get the speedies late at night and start yowling. Whenever I leave for work, I can hear her yowling all the way outside. She also hates when I’m moving around the house to clean. She gets all the attention in the world and she’s spoiled rotten. I gave her 2 of these supplements earlier just to see how she would react, and they seem to be working? I’ll have to try again at night or whenever I leave the house because that’s when she seems to get triggered the most. I think it has something to do with separation anxiety. Let’s hope this works!

They loved the flavor

My Vet recommended these to calm two of my kitties, they had no issues eating them but I did not see any changes in their behavior. It doesn't mean it won't work for other cats, it is a great brand that My Vet and I trust but I think they need something stronger.

Will Not Eat

I can not get any of my cats to eat these. I have tried cutting them with no luck. They will put them in their mouth then just spit them out. Tried breaking up and mixing with their favorite treats and they then refuse to eat the treat. No idea if they work if the cat does eat them.

Treats too big

The treats themselves are too big, it would be better to cut in halves. My cats still didnt eat them though. I guess they didnt like how they smell

no idea if it works because he won't eat it

I let him sniff it and he seemed interested initially and tried to put it in his mouth. Spit it out immediately, so I thought maybe it was just too big for him and broke it up for him. Did not want to put it back in his mouth. Put it on top of his kibble in case he changed his mind. Did not touch the kibble for a day, eventually ate his kibble but did not touch the treat.

Minimum calm

Sadly, this product did not live up to the hype. It did absolutely nothing to calm my cat. There is a coding that she liked but once that was gone, the little fish shaped morsel laid there dead. It was truly a waste of money.
