Royal Canin Veterinary Diet Calm Formula Dry Cat Food 4.6 5 10 10
It Works! Our insane, manic, spastic 6-month old kitten ceased attacking the curtains, flying from speaker to refrigerator-top, assaulting other cats, climbing the light fixtures and calmed down just enough to let us see how much we love him. It's as if he swallowed "The Little Book of Calm" (though he chewed through the bag before I had a chance to serve the first portion). Our placid 9-year old cat would not be left out of the experiment, but we hope he'll wake up by New Years. December 18, 2012
Overall satisfaction I had to order this product on-line since I was away from home and needed this product fast ... our current supply was dwindling and had that sinking feeling of not being able to find it here. Ordered it on-line and it arrived within days even after having to get a prescription filled to complete the order. Not only does this product work wonders on our cat's behavior, the quality of service received was commendable. Thanks! February 15, 2014
This Calming Cat food is helping to restore cat tranquility. The calming cat food is helping to restore cat tranquility among our 3 cats. One of our cats was abused before we adopted him and he had never learned to play with other kittens and as a result caused us much anguish with attacking the other cats and urinating in the house. Since he stated on the calming cat food, the change in his behavior has been dramatic and we now have peace and harmony among all of our cats. has been superb in processing and delivering all of many orders in a prompt and efficient manner.

Kitties love the taste I gave this product to my four cats knowing my son was coming with his puppies. wild and crazy doggies they are. My cats are older 11--14. so they get nerves when the dogs come in and try and take over there home. Even my 9 year old lab tries to get in on all the wildness. Any way four days before the monster puppies came I started feed this food Calm to the kitties. What a difference it made. they didn't run and hit the stayed in the room we were in even if the dogs going crazy. and the cats liked the food. I am going to get this for my sons dogs and maybe my daughters dogs to August 4, 2013
Pleasantly surprised I was skeptical when the vet prescribed a "calming" cat food to try to curb my cats' new territorial behaviors. I don't event think his expectations were high - he had not tried this before. I was also concerned that the ingredients were not as good as the food I had been using but I had tried everything else without success so I bought a bag of Royal Canin Calming food. The cats love this food and they do seem to have calmed down so I will likely purchase again despite the expense. July 16, 2013
Jury's out on this product I've been feeding this product to my 3 cats for about 2 weeks. They love it but haven't seen any effects yet. Will post again in about a month. April 12, 2013
Just what my cat needed My cat, Fraidy has always been afraid of thunderstorms. Now the thunderstorms bring on asthma attacks. This food works wonders! I could tell a difference with his anxiety after a couple of days!! I would recommend this food to anyone with a cat with anxiety issues. July 11, 2014
It works quickly!!! I have a total of 10 cats in my home. Some just don't get along. I saw this food and decided, "why not" . Well, all of the cats (8 + 2 fosters) just LOVE this food! It seems to be working and I started it three days ago. Highly recommend. Getting vet okay took a bit of time, but they authorized it. Thanks for going that little bit extra. July 1, 2014
