The Royal Canin Veterinary Diet Calm formula is designed for cats. It include two amino acids that help pets maintain emotional balance. Alpha-casozepine is an amino acid chain derived from milk shown to have calming effects. L-tryptophan  is a more commonly known amino acid that also has calming effects. In addition, the formulas include Nicotinamide, also known as Vitamin B3. Nicotinamide creates a calming effect within the central nervous system.

Key Benefits

  • Contains a hydrolyzed milk protein and tryptophan (anaminoacid) to help maintain emotional balance of the cat
  • Precise amounts of B vitamins and amino acids to help maintain the skin's natural barrier effect
  • Specific nutrient blend to help regulate intestinal transit and to help support beneficial digestive flora
  • This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalatecrystals
  • A combination of fibers encourages normal intestinal transit and the elimination of hairballs in stools

Rated 4.7 out of 5 by 45 reviewers.
Rated 5 out of 5 by Repeated Success A few years ago, after medication did not affect our alpha female from marking, our vet suggested this food. Boom!! In less than 2 weeks she completely stopped marking and picking on our other kitties! After a few months we switched her back to her usual IAMS dry food and have not had the problem since then. We took in a sweet little female stray who was in our backyard for a couple of years. She was tame and we brought her in at night to sleep with us. No problem, right? Well, she got into rat poison at our neighbor's and she fell ill. We now had the task of making her an indoor kitty. She was not doing well with this, so we put her on this food and the transition is going so much better! It is still a work in progress with her, but she is adjusting and finally allowing us to sleep at night without crying at the doors and windows all night. Our other kitties eat this food, too, including our previously mentioned alpha female who did not welcome another girl into the house. Buy this if your cat needs help with any type of emotional adjustments to their environment or the introduction of a new pet. It works! July 25, 2016
Rated 5 out of 5 by Helped settle feral so she actually came to me to let me pet her. I do rescue and TNR so I often have scared feral cats and kittens that I am caring for on top of my 6 feral converts that I have. I have spent thousands trying every available products over the years trying to help calm cats under my care. Defusors in every plug in, sprays and chewies and calming collsrs and coats. Ive even used prescribed meds over the years. I had been reading on this product wanting to try it and finally got my vet to authorize prescription. I started with my 3, 8 month old ferals that I am fosterring. I saw a difference rather quickly. Heard their purring and then after only a few short days Mitzy a feral that I had never been able to pet allowed me to pet her. That same day I had my vet authorize scripts for all my cats to switch over. I am happy customer. It cant turn them into pets but it is a useful tool that helps me work with them. Another good thing is that all the cats love the food. Something that never happens in my household. I want to share that the distributor actually gave me my first bag free because she heard I was trialing it with ferals. I thought that was nice. I love this product and now because Chewy has the best prices Im getting script to start ordering it through autoship. July 15, 2016
Rated 4 out of 5 by royal canin Vet Diet calm formula We purchased this food for our orange tabby Butterfinger. He is usually a fairly docile guy, however not riding in the car. We tried most everything including medication. We did not like the meds they made him really out of it. So we thought to try the calm formula. So far it has done a decent job. He still is not happy about riding in the car but he calms down after a bit and settles down. We take trips that last up to 6 hours, so he calms down after about one hour. Much better then six hours of meowing. May 12, 2016
Rated 5 out of 5 by both cats like it Only dry food they haven't thrown up. But I do limit their intake. I like for them to have dry food available all day to graze but haven't found one they don't throw up when I do that. I haven't tryed doing it with this one. May 14, 2016
Rated 5 out of 5 by Helps Calm a Nervous Kitty The food has helped our cat. He is calmer and doesn't seem upset when left alone. He is a picky eater, but gobbles this dry food down. May 11, 2016
Rated 2 out of 5 by does not help with territorial spraying or aggression. hoped this would eliminate need for Prozac for one of my neutered males who sprays. has not helped with that issue or bullying issues after almost 4 weeks with all cats on this diet. April 7, 2016
Rated 5 out of 5 by Excellent product I got this for a foster cat returning to his home, an 11 hour drive. It worked! All my cats liked it and my older cat eats it and is more social. He now hangs out with the younger ones. I did need approval from my vet as it is a prescription food but that did not affect the great delivery from Chewy. Glad Chewy offers food types I was not aware of. March 31, 2016
Rated 5 out of 5 by Fantastic food! All nine kitties love it. I have nine kitties of all ages- the oldest is 18. Two are on special diets but do well with Calm. One rescued recently was so skiddish we couldn't pet him. He is now a lap cat. Others that were not overly friendly have become playful and lovable. March 31, 2016
