Product Description

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

NOTE: Royal Canin veterinary diets require a veterinary prescription. This product will not be shipped until a copy of a valid prescription authorization is faxed to 1-800-619-7973 or e-mailed to

Rated 4.7 out of 5 by 43 reviewers.
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
Rated 5 out of 5 by This Feline formula does have calming ingredients. My vet wanted me to try this formula for my female feline who loves to eat kibble more than her wet foods. After giving a small portion of this kibble I notice that she does seem to calm down after about 10-15 mins. However, in the a.m., she wants more kibble again and thus, I have this calm to give to her. March 21, 2016
Rated 5 out of 5 by Product saved my cats life My 2 yr. old male cat had crystals in his urine which caused a blockage (medical emergency)! The vet gave me free samples of another brand of food to feed him until I received the Royal Canin. He would not touch it and I was afraid of the same thing with this brand, but HE LOVES IT! Best thing is the Royal Canin dissolves the crystals and keeps calcium stones from forming too! And it passes the taste test! Worth the health of my Bear. And it lasts a full month or more. Fast delivery. March 1, 2016
