They worked!

We just moved and one of our cats Kaida loves the place but has been experiencing some minor aggressive behaviors towards his brother who he adores. We talked to

We just moved and one of our cats Kaida loves the place but has been experiencing some minor aggressive behaviors towards his brother who he adores. We talked to our vet and they think he is experiencing jealousy towards him triggered by the anxiety of the move. Our vet recommended these calming treats. We have used the Vetriscience brand for Vetri Lysine Plus when Kaida and one of his brothers had an eye infection and they helped a lot. We had high hopes! Genuinely these treats have worked so well for our little one. For a month now we were not getting any sleep and this has helped him sleep or stay calm during the night without him being loopy or lethargic - which was super important to me. He is back to his old self and has no behavioral issues when using these treats. He gets so excited when I grab the bag and will jump up and meow like it’s any other favorite treat of his. I would highly recommend giving this a try for your cats if they struggle with anxiety or minor behavioral issues!

Soft chews

the first pack I received was soft and chewy. The second pack seemed dried out and none of the cats like it now.

Amazing stuff!

My cat was freaked out by a thunderstorm, so I tried giving him one. Within 10 minutes he was much calmer, and stayed that way throughout the day.

Stop Messing with the Flavors!

I have used Composure calming treats for many years. They were effective after approximately 40 minutes. But the manufacturer started offering different flavors of the product & I started having trouble getting my cats to eat them. They completely reject the Chicken flavor. I've had better luck with Trout, but nothing is as popular as the original flavor. I wish it were still an option!

Not sure if they provided much relief

Bought these to calm my kitties during roof work on my house. Saw others say their cats didn't like the taste. My cats were ok with flavor. It was a semi soft treat. A bit large for my female cat, I was easily able to break one in half for her. Cats still were both super nervous. I gave them a second treat mid day, that didn't seem to make them any calmer.

Minimal healthy ingredients & very good results, without the use of chemicals. Unfortunately, my cat does not like the flavor & is refusing this calming treat. I will save it & try again at a future date. My cat was not knocked out by this. He was playing & interacting with me, without going overboard & scratching me. No aggression noted. I highly recommend it.

They wouldn't eat them

They wouldn't eat them. What one cat will eat others won't. You never know until you try.

Doesn’t calm her down/smells atrocious

I’d put the treat down for my cat to eat. That spot where I placed it would then stink like something died. I literally looked for a carcass in my apt even as I knew it was absurd to do so.
