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.

  • Works to calm our feisty older cat and timid younger cat

    By on

    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.

  • It works!

    By on

    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.

  • For some reason this product works!

    By on

    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!

  • My babies love this!

    By on

    My 3 cats love this and they are very picky. The first day I got it they became so calm and sleepy. But now that they got used to it they act like their normal self but still has that calming effect. So it does work!

  • It seems to help my cat!

    By on

    My cat has been licking off his fur. He immediately started eating the specialty cat food. He seems more calm. I intend to continue him on this food (auto-ship). It's easy to set up the order in conjunction with the vet's authorization.

  • Great food for my cat

    My cat was pulling out his hair and the vet treated him for fleas and recommended this food. He is so much better now. This food seems to be working for him. Thank You

  • Wiley's favorite!

    By on

    Wiley (16 yo) has been urinating outside the litter box and "Calm" helps him behave! "Calm" is part of a number of things I'm doing to encourage him to use the litter box. Wiley is extremely thin and is eating the "Calm" very well.

  • Cat 360

    By on

    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!!

  • The reviews are true!

    By on

    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 $$$

  • Calming healthy catfood

    By on

    Our vet recommended this Calm formula catfood when we introduced a younger rescue kitty to our older kitty. It's worked very well for calming and also keeping a healthy urinary tract. I add some Canin hairball dry food in too. My only complaint is the grains in it. We all prefer grain free.... hopefully Canin will catch up with the times. ☺ REALLY LOVE the convenience and good price from Chewy! Thanks guys!
