And it keeps him healthy.

My cat is not very finicky and he loves kibbles/dry food, so this has been great.

I made the "rookie mistake" of giving my cat some Dollar store cat treats and it caused him to develop urinary stones for the first time in his life. Big mistake, especially from someone who was raised by a vet mom and who lived above a vet clinic for 2 years as a child.

After some major emergency expenses and antibiotics, my cat got better. My mom then had me get some of this S/O urinary cat food as an "insurance policy" to make sure the cat urinary blockage never occurs again and mix it into his regular cat food (which is now regular Royal Canin Feline Indoor 40, for weight maintenance). The reason I can mix this Urinary S/O food at about 20% and 80% of the regular Indoor 40 food is because my cat doesn't have stones developing in his system, this is just a preventative maintenance thing. If your own cat has serious urinary problems, you may need to go full strength on the S/O food, but talk to your vet about it.

In any case, I initially gave him the regular S/O urinary food and he started to gain some weight, so I switched him to this S/O urinary moderate calorie and it seems to have kept any weight gain at bay. :)

I am very pleased with the product and will continue to order it. My cat is not very finicky and he loves kibbles/dry food, so this has been great. If your cat is a "wet food eater", try the canned version of this product. I am very happy with the dry, as he likes it, it is low calorie, and no more urinary problems. :)

Ps. This is not intended to substituted vet advice about urinary problems. It is important to discuss your cat's medical issues with your vet. And if your cat cannot urinate, is crying, and leaking urine, that is a medical emergency. This food will not fix that, only help to prevent urinary blockages.

I used this cat food for 5 years because it was recommended by my vet. I am sick over what I have done to my cats for those years of their lives.

I have a female cat who often had urinary blockages due to crystals, and a male cat who is relatively healthy. When my female cat was getting UTI's a few times a year, I was given a few "Veterinary Diets" to try. Royal Canin was the last one, because she didn't like most of them. I knew the ingredients weren't great: they included things like corn and wheat gluten (now switched to soy gluten, I believe). But I thought it was the only way to keep my female cat healthy. And my male cat liked it enough. But over the years, my cats, especially my male cat, got heavier and more sluggish.

So for 5 years we fed them this less than good food, thinking it was the best we could do for them. Then my female cat got a UTI's again after a while, and I was miffed. I no longer thought this was the best I could do anymore. If it wasn't going to keep my female from getting UTI's, then there was no reason to give them this inferior food. I looked into exactly what it was that made Royal Canin's "SO" formula. I discovered it was largely DL-Methionine. Methionine acidifies your cat's urine, which in turn dissolves the crystals. Struvite crystals are also caused by not enough water, like from feeding dry cat food. Unfortunately, you have to know that there are two reasons that make your cats have UTI-- struvite crystals (the cause of the vast majority of UTI's in cats) which is helped by Methionine, and the other kind, which can be harmed by further acidifying from the Methionine. However, if your vet has already determined that Royal Canin Urinary SO is what you should feed your cat, then it's likely that struvite crystals are the cause.

It is completely my fault, but I had several different sites pulled up to compare prices, and failed to realise that this was a very small bag of food. I normally get over 7 pounds from the vet for $33, and was thinking this bag was the same size. in comparison, this bag which is half the size was much more expensive. So it is for this reason I gave a low rating...the price. The food seems to work great.

This is expensive, but normally you need to buy it from a vet with a prescription. My cat had a severe UTI, and my vet told me to keep him on urinary SO. I did for a while, then reverted to a good pet store brand, and my cat got another UTI. So he's staying on this stuff now. My cat lost a pound on the moderate calorie formula, and has maintained a good weight since.

Have tried many of the prescription foods and this is the only food my three cats like. While its pricey it is certainly less than the $4000 (really) I spent on vet bills for one of them. Wish I had put the cats on this earlier maybe I could have saved the money and the pain for my cat, he was miserable.

I buy food online occasionally when I don't have time to go to the vets office to buy a new bag. This comes in handy as a extra bag to use for those "in between times". The bag came sealed and packaged well to prevent tears.
