Rated 5 out of 5 by from Our kitty has been eating this food for a few years now by the recommendation of our vet, Dr. Rachel Savoy for urine tract issues because she has a tendency to have 2 different kinds of crystals in her urine.

Rated 5 out of 5 by from My cat loves it! When the vet wanted to change Oliver's diet following surgery, I was really concerned that he wouldn't like it. Luckily, I was wrong - he gobbled it down from day 1. Thanks for making your food so appealing!

Rated 5 out of 5 by from Saving Lives My beloved Gray Cat had crystals in his urethra and could not potty. He had to have surgery to help him urinate again. Our vet prescribed Royal Canin Urinary SO canned and dry food for our feline family member. He has been eating it for over a year now and has no issues at all. We even write down on our calendar daily potty habits so we know for sure how many times is urinates. Thank You Rayol Canin for making such a great food choice for our kitty!!!!

Rated 5 out of 5 by from My After my cat had a urinary blockage my vet recommended Royal Canin Urinary s/o food to help us avoid future surgery. It's been more than 4 years that my Sam has been enjoying this food and no more blockages. Even better is that once he started eating Royal Canon food his allergies cleared up. I never realized that what we were feeding him before was contributing to him almost scratching his eyebrows hairless. He's about 10 years old now and has the energy he had back when he was two. Truly amazing and grateful.

Rated 5 out of 5 by from Saved My Cat Due to my cat continually get stones in his bladder, I changed his food over to an all wet food diet and Royal Canin Feline Urinary SO Moderate Calorie. Since he is an indoor cat, I was worried about him gaining weight. He has been on this product off and on since October 2014. Due to the cost, I would change him back to a cheaper brand. Well, my mistake...he got stones again and we went through another costly operation to have the stones removed. He is back on Royal Canin since November 2015 and has been doing great. He will be on this brand for the rest of his life. So happy that there is a product out there that will keep my cat from getting more stones. Thank you Royal Canin!

Rated 5 out of 5 by from My cat loves to eat this product! My male cat had an emergency situation a couple months ago and he had what is called "Blocked Tom". The WONDERFUL veternarian that saved his life prescribed this food for him and he has been eating it ever since with no problems, meaning he enjoys it and readily eats it (not finnicky) and has been peeing better and better, too. I am so thankful for this Royal Canin food made specifically for cats with this health problem because my cat has been feeling better and better since he started eating this food. And he really likes it and looks forward to eating it twice a day that I feed him! Thank you for your great product. It definately has kept my cat feeling well I really do believe that.

Rated 5 out of 5 by from Cats can't get enough of this! I recently had to switch my cats to the Urinary SO line and noticed they had "moderate calorie" options. Given my cats are a bit on the chubby side I chose the moderate calorie version, hoping they would not turn their noses up at it. To be on the safe side I also bought some of the regular (calorie) urinary SO food too. I wad thrilled when all three immediately gobbled up the moderate calorie version! It's wonderful that Royal Canin provides an option for meeting two needs (crytal formation & weight issues) in one product.

Rated 5 out of 5 by from The only one that keeps the crystals away My boys have been on this good for a few years now because one has FUS. THIS IS THE ONLY wet food that has been able to consistently keep him clear of crystals and blockages. We've also tried the Royal Canin Satiety Support with S/O index, but he got severely constipated and ended up with a urinary/bladder infection. I trust this food (and the dry conterpart as well), it helped him when Science Diet formulas only made him worse. Thank you for making a good good that keeps my fat little man clear!
