Work so well

I have a very nervous, stressed out kitty who would prefer to be an only cat in a home with 11 cats. The Calm food does just that, takes the "edge" off and makes her more comfortable and less afraid. I believe this food gives her a better life. And....it must taste wonderful because my other cats steal it whenever they can!

It Works!

Butters has always had behavioral problems as well as urinary issues. After my vet recommended this food, he no longer punishes me with urinating on my belongings!

Amazing results!!!!

My kitty Pipsqueak was a fluffy bundle of nerves that would hide and bolt at any of my roommates that came home, new people, or any noise. Now he just chills, still doesn’t like anyone but me, but he doesn’t bolt anymore. And always meowing for more food!!!

Crazy about Calm for Cats

Tried this product over a couple years ago and I have been thrilled with the results I've seen in my cat.

Calm really keeps cats happy

I work at a Veterinary clinic and bought a bag to try it on our clients. 100% of client cats showed improvement, easier to handle and more social at home.

Actually works!

I have been using royal canin Rx calm food for my cats for a couple of years now. Because my cats are all formerly semi-feral cats who were brought in from outside, i find the calm formula helps everyone get along better and be less nervous.

Didn't work for us

The vet suggested that I try this food but my cats didn't like it very well. I continued to mix in with their other dry food but didn't buy more when it was gone.

We loved this product!

This food seemed to be very effective in easing some of my cat's negative behaviors. Best of all, he liked it, and he is extremely picky.

Great Food!

I have been using this food for a few years and I love it. I have a 2 cat household and this product has helped keep both cats have a calm attitude towards each other. When we ran out of this food for a few days it was very noticeable that there was a difference in their attitude.
