Royal Canin Veterinary Diet Feline Urinary SO in Gel Canned Cat Food

Royal Canin Veterinary Diet Urinary SO Moderate Calorie Dry Cat Food, 6.6 lb.
My female miniature poodle had bladder stones removed surgically and was put on a diet of Hill's multipurpose C/D. I started feeding it to my Yorkie and he was eating it but the kernels were large and I thought I would try the Royal Canin. They did not have the small dog so I fed him the large regular SO. He started vomiting and getting loose stool. I took it back to the vet and they ordered the small bite. While I was waving for the small bite to come in I switched to Hill's again with no problem. I picked up the small bite when it came in and the Yorkie got loose stool then diarrhea and vomiting. Last night I took him to emergency because of black stool. He was diagnosed with blood in his urinary tract. There was no signs of parasites and they did blood work which looked normal. The vet put him on special medication for a week. I suspect that the food has caused the problem and after spending $240 I am taking the food back to the vet.

A urinary tract infection (UTI) is a bummer, especially when it is affecting your cat. Often the result of crystals or other calcified growths appearing in the urinary tract, getting rid of these painful obstructions can be tricky. If your cat is susceptible to, or has a history with, UTIs, often a medicated treatment option is required. Rather than trying to get your cat to take a pill, or worse, a shot, medicated foods, like the Royal Canin Veterinary Diet Urinary SO Canned Cat Food, can be one of your best options.

Due to blood in urine, I have been feeding my cats Royal Canin Urinary S/O for about 5 or 6 years. They each get 1/3 cup of dry in the morning and evening, and 1/4 can wet in the afternoon. All was well until about March 2017 when one cat was vomiting regularly. Vet did Xrays, bloodwork, etc. and no issues determined. Switched to a Royal Canin "bland" food which the wet worked fine but too much of the dry gave her diarrhea. Slowly mixed bland and S/O to get her back on track and it was fine. Then switched to all S/O and in 1 day she was vomiting again. Other cat seems to have no issues. I'm guessing Royal Canin had a formula change and it is detrimental to some animals. Used to be good, now cat vomits regularly.Follow-up research of Royal Canin Urinary SO has found that severe, debilitating constipation, such as what affected our cat, is a common issue in both dogs and cats. Reading all the other consumer complaints, I find it irresponsible for any vet to recommend RC food. My vet has sent RC my complaint, my invoice and photos of the bag of food we still have (not using of course). The vet had been told by RC that there have not been any complaints to the company about this product. This was the first, and that my info has gone to their consumer relations department. To date I have not heard anything from RC directly. I would suggest everyone here who has had issue with RC contact them directly.We had one cat who had a urinary blockage and the vet suggested we start feeding him Royal Canin S/O wet and dry. We were told that it would be fine for both cats. The first case of wet food was fine but the second had a different consistency, almost as if they changed their processing. After being on the food for just over a month, our second cat became extremely ill, constipated and throwing up. We took him back to the vet and both attending vets inquired to any recent changes in diet, acknowledging that such a change could be the cause of his potentially deadly issue. He was so backed up that sedation was required to help clear him out. Needless to say the poor thing has never really recovered. My elderly cat was diagnosed with renal issues during a recent wellness visit. The vet recommended Royal Canin Renal Support, and I bought a kit with several different flavors of wet and a small bag of dry food. Within 12 hours of the first meal my cat started puking and pooping all over. The poop was green and extremely smelly. Poor kitty was sick all night. By morning she was clearly uncomfortable but at least drinking water. I threw away all remaining food including unopened cans so no one else's cat suffers like this from this food. 12 hours later back on her old food she's eating well, drinking water and while still a bit fragile. She is much better, no puke or poop all over. After reading other reviews I am convinced that I made a bad decision by trying this food and I'm posting to warn others. Photos of the bag with numbers are attached.
