Questions & Answers

30 Customer Questions

Is this available as canned / wet food?
Answer by ChewyJan 26, 2018
Royal Canin currently makes this formula as a dry food only. It is not available in a can.

Do you carry Royal Canin dry cat food Urine & Calm? IF so, how much and what are the sizes offered?
Answer by ChewyJul 27, 2018
At this time, we don't carry the Urinary + Calm formula veterinary formula.

Does it cause cats to sleep more than usual?
Answer by ChewyOct 20, 2017
The Calming food relaxes the cat so it could be so relaxed it naps more than usual but we'd recommend consulting with your vet if it persists or naps get longer.

Does this food require a prescription?
Answer by ChewyJun 09, 2021
Because Royal Canin Veterinary Diet Calm Formula Dry Cat Food is formulated for medical issues, veterinary authorization is needed.

This stuff Works!!!

We have an aggressive cat, and he has slowly began to attack one of the smaller ones. I read some reviews and thought we would give it a chance. He loves the taste, and I truly think he is less aggressive. Not completely gone, but better for sure. It is expensive, but we will keep buying it because it works!

Highly recommend

One of my cats has anxiety. My vet prescribed this dry cat food for him. This Royal Canin Calm has made a remarkable difference in his anxiety. He is calm and relaxed now. He likes the flavor and so does my other cat ( who doesn’t need it but wants to eat it too). I am so thankful my vet recommended this food.

My Cat's Favorite

This dry food, which is served along with wet food is my cat’s favorite dry food. On occasion, I put out an additional dry food to provide the cat with variety. One of the alternatives is to help prevent hairballs and the other is to support dental health. They are eaten, but only after the Calm is gone. During the recent short period of time when Calm was not available, I panicked. I was not sure that my cat would survive it. We made it through all right. I am truly thankful that Calm is available again! We are going to start our second bag since Calm has been back!!

Definitely Worth Trying for Feline Territory Issues!

We have 5 cats and after 6 years, a territory marking issue started - caused by intimidation of 10 yr old shyest kitty by two others. We have been feeding these 3 kitties the Calm food for almost two weeks now. We definitely believe this food is helping to keep personalities calm (no marking). It is very expensive, but when you are faced with no alternatives (not possible to rehome marking cat), it is definitely worth it!

Yah, Finally Found Something That Works

My little feral cat does well on this. She used to have litter pan avoidance issues but with this food and Dr. Elsey's Cat Attract litter, she does great.

My cat loves this stuff

My cat had been eating Royal Canin Urinary S/O food and was doing OK with it, but she really likes the Calm formula that also has the S/O index. Our vet recommended this because the cat seemed kind of skittish. The cat has been eating this for two weeks now. She loves it, has no issues digesting it and is very happy.

Excellent service

Placed our order and had it sent to vet in FL where we were on vacation. Staff at vet's office refused the package and when we found out, we called to have the order sent to our home address. Turns out the chewy order got home before we did!! Even with this misunderstanding. Think that's pretty impressive service. Thank you!!

RC Calm Rx diet

This helps my little red haired girl stay a bit calmer. She’s been known to “body check” her big sisters but it isn’t done in a playful way. She also gets the RC Urinary Rx’d diet. Please check the expiration dates on your bags. This one was delivered a few minutes ago. It’s been ongoing and I recently noticed.

My problem children

So I have four gorgeous neutered Persian boys. They are my life. But two of them have anxiety/dominance issues. Fritzi is very shy with everyone except me. He hisses and hides if someone comes over. With me, he is an angel. Loving and funny. But he has severe anxiety even if he just hears a noise from outside, sometimes I can’t even tell what triggered the anxiety, but he even hides from me. He started to lose weight on a food that is actually higher in calories than this one. Since he eats this food, the anxiety attacks are gone and he is gaining weight. I am not saying I like the ingredients but I can’t deny it is working and helps him a lot. My other baby: Jamie is the smallest and most fragile of all four BUT he thinks he could beat a lion. And he is very territorial. Also out of nowhere sometimes he wakes from his sleep and runs to the back porch door growling, looking out but there is nothing there. After an episode like this, he is on edge for days. Also he picks on anyone who dares to sleep on any of “his” thirteen cat trees but since he eats this, he completely changed. And immediately, like in a few hours. Since then there is no picking fights, no edgy behavior and he is active, playful and energetic. So I would say this food is magic. Oh and they like it too. He is usually picky but eats this like an excavator.

So far so good!

I started adding this to my cats’ food (I have 4) a day or two before I left for vacation. My house sitter reports my house does not smell. This is significant in that usually my two younger males spray my walls when I’m gone and it’s nasty!! Fingers crossed! I’m currently mixing it half and half at least.
