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.

Great idea in theory

I was really surprised how hard these were. I had hopped for something a little softer, especially since I was giving them to an 11 year old. That being said, she won’t even entertain the idea of them. I’m always looking for ways for my pets to be less stressed and with my increased work schedule I had high hopes this could help her, but back to the drawing board we go!

I got these because my cat hates getting his ears cleaned. He is about 10lbs so I gave him two and then waited 15 mins and cleaned his ears and he didn't seem as bothered as he normally does... However, an hour later he was relaxed as could be because he fell asleep in his litter box, like limp noodle sleep! My cats would not eat the treat unless i broke it into pieces. I will definitely replace when the time calls for it. Every cat is different but i would start off with just one or two chews and see how it goes.

Product works so well! Night and day difference

At first, the only time she would sort of eat it was in her food only to have mild results for a short period of time and then go back to crying again. Plus, her food would not be empty by next feeding time, which was a bit of a concern. But luckily she loves those puree treats. So, after looking at some other reviews of tbis product, i figured I'd grind it super fine, and mixing it in a table spoon with the treat and give it a shot. She eats the full dose in less than 2 minutes and can go back to enjoying her regular food. Great bonding experience when she eats the treat, so she feels rewarded. Also, dont be afraid to give 2 on especially anxious days. These treats work especially well with night time crying and other anxious behavior such as biting/scratching and attacking furniture. These treats, along with pheromone spray diffusers have helped her adjust to her new home and be comfortable.

Calming supplement

This product seemed to help one of my cats who is being stressed out by the others. I ran out already, I was also giving it to the other cats to calm them down as well. I will have to order more, it seemed like it was helping.

First time ordering, deisred results with this item

This product is already proving helpful in my work with the shy, fearful cats at a nearby shelter. I particularly noticed reduced anxiety with two cats. A short while after each of them had received one chew, each cat was more relaxed.

Didn't work for us

I bought these because we got a third cat and one of my other cats isn't handling it well despite the new cat being very sweet and gentle. Unfortunately, there was no improvement whatsoever with my other cat's anxiety after a full week of taking the maximum dosage every day. It might be because his reaction seems pretty severe (he literally screams) so these are probably for mild to moderate anxiety.

I give these treats to my cat right before cleaning day or if I have a long day at work and have less time to hang out with her. They put her to sleep -- not like Xanax, but more like melatonin. She seems to like the taste, too!

Actually works and fast results

I had tried a few different brands of calmative treats from the local pet stores. Only one brand calmed our cats down but one cat wouldn't eat the treats unless we mixed it with something else. I saw these here on chewy and I was familiar with the brand as we feed their lysine treats so I thought I'd give them a try. These treats were the winners!! Both cats will eat the treats no problem, and with two treats each it's nap time. Two weeks ago these treats proved their worth. We had a tornado warning + thunder storm so we were all hunkered down in our tiny bathroom for about an hour. The treats started working within 20 minutes, both girls just laid down and took a nap. Would highly recommend these for just in case purposes!

Very smart

He caught on how the chews calmed him and knocked him out. So he doesn't go crazy over them anymore. I dissolve 2 in warm water and use a medicine dropper to put some in his soft food.

cats won't eat them

My anxious fussy older cats wouldn't touch these after the first taste. But neither will my 9-month-old who loves just about everything. So I have no idea if they help with calming, but extra brushing does, so I'll save my money.
