Product Reviews
Royal Canin Veterinary Diet ® Feline Multifunction Urinary + Calm dry cat food is rated 4.6 out of 5 by 48.
Rated 5 out of 5 by from Best for feline cyctitis When my poor baby was so sick with uti that the lining of her bladder was thickened and bleeding. The Dr medicated her but informed us that it was a long term treatment including diet change. He ordered her a bag of the RC feline urinary multicare with calm. She slept for a few days but once she started munching on the kibble. I knew she was going to be okay.

Rated 5 out of 5 by from Magic! I just got back from the vet and I needed to come write a review to say this food is nothing short of magical. A month ago they found a pretty massive bladder stone in my neutered male cat, Inky and recommended this food to help dissolve the stone. After two weeks I could see a noticeable difference in his litter habits, and today, just a month later, the vet says there is no sign of the stone! Don't underestimate how well this food can work!

Rated 5 out of 5 by from Cat loves My cat is very eager to eat this food. He has a history of cystitis but needs to eat at least some dry food in order to get enough calories. This food works well for him and the added calming ingredients seem to reduce his stress.

Rated 5 out of 5 by from Works Great! I absolutely LOVE, LOVE, LOVE this food. I am an RVT so I see pets come in all the time that have urinary issues. I have 3 cats, 2 of which need a urinary diet. 1 of my cats also has anxiety issues to go along with his urinary issues. I have tried to use different medications for him, but catching him and giving him meds just made him more scared and anxious so I tried this food and let me tell you. It is like he is a whole new cat! He will still run from people when they come to our house, but our family is able to see him now and the only time he runs from us is when he knows we are going to "do something to him" like trim his nails or take him to the vet. It is also a food that we are able to feed our other cat with urinary issues so that we don't have to get a separate food for him too. I would and do recommend this food to a lot of the clients that I see who's pets seem to have similar issues that our cat has and they all come back and say how great it works. It does take a few weeks for you to see a definite change, but trust me, IT WORKS!!! Kudos to you RC! You are awesome!!!

Rated 5 out of 5 by from Has kept my cat's crystal formation under control, and has also made him "settle down" a little bit since starting. Great diet for a crystal-prone cat who can be a little feisty!

Rated 5 out of 5 by from Gambino the Great is a new kitty! Gambino the Great has been on SO-Calm since Nov 2015. It has changed him greatly. I love the changes. His health has improved. He is happier. I'm happier! I've recomended it to my friend whose cat has a severe uti- her vet agreed!

Rated 5 out of 5 by from Delicious and healthy My girl cat had contracted two urinary tract infections and the vet recommended the urinary formula for my girl. She has no issues since switching, it's been a few years. The calorie control came into play when my boy starting having impacted glands. So far, the formula works for both. My cats are healthy and not overweight. It's a win win for both cats. Yay!

Rated 4 out of 5 by from This really works!! This food not only offers the great qualities of Royal Canin's Urinary SO, but also has a calming effect on cats! When I first tried this food I was skeptical as to if it would actually make a difference in my cats behavior, but by time my first 17 pound bag was gone, there was no more stress grooming or fussing among my two very opinionated Bengals.

Rated 5 out of 5 by from God sent I tried this as a last resort for my 3 ur old cat the refused to use a litter box and had recently started urinating innapropratly. Tried all behavioral meds and pheromones nothing worked. Didn't hundreds of dollars I need testing and nothing was wrong physically. Tried this food and 24-48 hrs later I have not had to clean up urine anywhere.

Rated 5 out of 5 by from THANKS FOR SUCH GREAT FOOD! My Vet prescribed this food for my male Ragdoll that was having recurrent UTI's. What a miracle diet! Sunny Boy loves this food! To my surprise, my other Ragdoll girls prefer it too. They won't even touch the other brand they were raised on. Finally, UTI problem gone! Thank you for your commitment to making our animals healthy and satisfied!

Rated 5 out of 5 by from Anxiety bladder... My cat, Chep, has been on this food for over a year now. In October 2016 his urethra became blocked with sediment. He also had a large number of struvite crystals in his urine sediment. A culture came back negative for any bacteria. Basically my sweet, loving Chep had so much anxiety that he screwed up his bladder. We monitored his bladder through ultrasound while he was on SD c/d Stress. His crystal count never decreased as well as his sediment amount that we saw under ultrasound. We began RC SO Calm after a PU surgery as well as him becoming blocked 4 times within 6 months. Chep will continue to be given this food for the rest of his life because it is the only food that has dramatically decreased his sediment amount as well as called his overall anxiety for the past year. He plays more, interacts lovingly with our other pets, and wants more attention now. It's like my sweet, docile cat has came out of his shell and is now showing his true self. I couldn't be happier.

Rated 5 out of 5 by from Royal Canin Urinary SO Veterinary Diet I have been using this formula for the past year or so for my 5 indoor cats even though only one cat really needs it. I am happy to say that they all love it. It is very difficult to feed separately, so I am happy that they like it! I did try the canned food in this formula but did not have success with it.

Rated 5 out of 5 by from Healthy and Happy In a house of mostly male cats one of my biggest concerns is urinary health. Also being a multi-cat household has it's own challenges and dynamics. Royal Canin's Urinary + Calm has given me piece of mind. Now I know that not only are my furbabies getting great nutrition but it also has amazing benefits!

Rated 5 out of 5 by from My babies loved it! Being on the food I did notice a calmer sense of environment at home. My babies still love the grate flavor of the Urinary SO and I loved the fact that the food seemed to balance out their hormones a bit. I noticed there wasn't as many arguments or cat fights around the house.

Rated 5 out of 5 by from Great for cats with reoccurring uti's My cat Haze kept getting UTI's and the vet prescribed her this and it fixed the problem. One week I ran out and tried another brand and in a week her UTI was back so this happening proved to me that the food was working and keeping her healthy! Love it!

Rated 5 out of 5 by from This diet changed my Cat's life. I rescued Dewey as a small kitten and from the start he was extremely aggressive and would attack if he felt threatened, I couldn't pet Dewey or have visitors over without him trying to attack. Along with Dewey’s aggression he will block when stressed, these stresses can be a visitor, moving furniture, changing my bed sheets, etc… I am constantly asked why I keep Dewey and the answer is simple, he needs a chance. He is reacting to experiences based off his unfortunate beginning. I have worked with Dewey in many ways over the years, but the biggest improvement occurred when I put him on this diet. The diet is formulated to prevent the development of both struvite and calcium oxalate crystals ensuring that Dewey doesn’t block and provides calming nutrients to help ease Dewey when facing stressful environmental situations. Since being on this diet Dewey has started playing, snuggling, I can hold and pet him, and he no longer charges visitors at the door. The diet has truly provided Dewey with the chance I knew he needed. I could not be more thrilled that he gets to live a long and happy life, thanks to Royal Canin.
