Highly Recommend

I had my 4 cats on this for months due to behavioral issues after 1 had a dental and fighting ensued. This is a wonderful food that really overtime helped calm all 4 of my cats down. I did have to use gabapentin on 1 cat but this overall works great. It did take a few months for the uptake of all the nutrients which is where the meds came into play but those were slowly tapered off and we had no bullying....and I tried EVERYTHING!.

Made for a nicer kitty!

My vet sold me this food after bladder stone removal surgery for my cat. She has always been fairly aloof and independent. After being on this food, she was a much different cat. She was more friendly and happy and didn't seem nearly as stressed. I switched to just the regular S/O food and noticed a big difference. The Calm food made her much nicer and relaxed.
Royal Canin response
Great to hear she is doing better!

I've been using Royal Canin calm dry cat food for almost a year now and it's made a huge difference. My 5-year-old male cat was suffering from anxiety-related bladder infections that can be deadly. I switched to this food and haven't had a single incident. It also helps manage weight. Fantastic product.

Love it!

I have 2 cats that sometimes don't get along as well. One of them was soiling in one spot. After using calm for a month I noticed they coexist so much better now. Thank you royal canine for making this formula. Happy mom of 2 cats!

Helps my anxious cat

My cat started having anxiety problems earlier this year. She was put on Prozac and eventually gabapentin as well. I also added this diet in for her and she has been doing better! She still hides a lot, but she will come to bed once in a while and she will leave the room she stays in to yell when it's time to eat :)

My cat was licking himself bald in areas due to stress. This calmed him so much, that his hair grew back quickly. He is happy now!

Good food

I had all my cats on this as a food trial for 8 weeks. They liked it although I didn't see any difference in their behavior. I was hoping it would help a little bit with stress related behavior but didn't notice any improvement

Amazing Affects On My Kitten

My kitten is now a year old but when I first got her she was 6 weeks old and was trapped. I started her with Kitten show mixed with the calm then weened her to just Calm until she was 9 months old. I truly believe that his products has helped her and calmed her and now she is a happy kitty

Makes a Difference

I have a male 8 yr old cat that has FIC. Trying to avoid putting him on Prozac. This food seems to help some with inappropriate urination.

Good stuff

Very helpful for my aggressive cat who would rather be an only cat - since starting Calm, she will actually come out and interact with people even if the other cats are around, hissing and swatting has decreased, household is much quieter.
