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.

Royal Canin Veterinary Diet Calm Formula Dry Cat Food is rated 4.7 out of 5 by 67.
Rated 3 out of 5 by from Great idea but ingredients are low quality and the price is high My vet who specializes in felines recommended this food. So I bought a bag. I had been feeding Orijen so I was used to spending a good amount on food but this Royal Canin food was nearly twice the cost. I would have gladly spent the money if it worked. I didn't notice any difference and when I checked the ingredients I saw byproduct meal as the number one ingredient followed by corn, rice, and wheat. Cats don't need all those grains so I am disgusted to have spent all that money on a food that is not that nutritious and doesn't work. My cats did love the taste though. Probably because it is like eating junk food. I will go back to Orijen.

Rated 5 out of 5 by from The reviews are true! My cat has been suffering from major behavioral issues for almost a year now. My new vet suggested this food. I was skeptical but within just a week of mixing it in with my cat's old kibble she is already starting to act like her old self. I could not be happier! Worth the $$$

Rated 5 out of 5 by from Cat 360 This food made a total difference in my cat. He's 10+ years old and he'd gotten completely finicky about any food & was skinny/skranny. Finally found something he likes & will eat...suggested by my vet. So grateful we tried it!!

Rated 5 out of 5 by from Excellent, costly but GOOD I initially was given this food because my cat was suffering from excessive allergies (itching/scratching/losing hair on paws) and a jealous attitude towards a homeless cat that I feed outside the house. The vet recommended that I change my ways and feed the stray cat at the side of the house and not right out front. Well, I did that and I also started using the calm food as recommended. My cat stopped the itching within 3 days of only feeding him calm. My cat liked this food from the start, I did not have to mix it with his old dry food. It also does not have a strong order as the N/D Royal Canin food does. The only thing is sometimes my cat eats fast and throws up so I just want to warn you if your cat does that, give him/her smaller portions instead of larger portions. I will continue to buy this food until I can find a good replacement at a cheaper price.

Rated 5 out of 5 by from Works to calm our feisty older cat and timid younger cat We have two cats. 1 is 10 very assertive, almost dog like, meows constantly and 1 cat who is 2 y/o, skittish all the time and is the brunt of the older cats energy. Before the food, the fights were daily, with fur pulled out of the younger, larger cat. Now, it's more like swats and hissing. The constant meowing sounds less insistent and more of just a vocal cat. After two years of cohabiting, this food, along with the pheromones collars work great. Both cats really love the taste and get worked up when they know it's meal time.

Rated 5 out of 5 by from It works! I've been fostering 3 feral cats from a hoarding case. One of the cats was so stressed that he lost a lot of his hair to overgrooming and also lost a lot of weight. A vet checked him out and we tried a number of different foods, supplements and probiotics to help him (along with feliway) but it wasn't until I tried this Royal Canin Calm formula that he started to significantly improve. I can't believe it actually works but it does! Highly recommend.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from For some reason this product works! I have three cats that don't get along to the extent that every time they see each other they literally fight. They've been on CALM for three weeks. They can now be in the same room without fighting, they give each other dirty looks but they're not fighting anymore, to me that is huge!
