Royal Canin Feline Urinary So Dry (7.7 Lb)

Ive purchased this product for a few months now for my 2.5yr old cat. He was having issues as he was always hungry and never satisfied with the amount of food he was getting so he would eat things he shouldn't... Vet had to perform surgery. Vet said cat has Urinary Issues hence being put on this expensive diet. The issues with cat always being hungry despite getting daily recommended food amount continues! Very frustrating! Another issue is Ive purchased the small bag 2x. The medium 2x and a bag of treats.  ALL of the resealable closures have broken! Its the bags/company not myself as I have other products with similar resealable closures that do continue to work.

Urinary SO

royalcanin.com/ca

This worked to dissolve and prevent struvite stones, but then suddenly the vomiting began. Thinking it was hairballs, I switched to the wet food—some old cans I had in case of emergency.,But when I bought new cans the vomiting escalated. She developed an aversion to the SO in any form Since my cat is overweight, she can get acute fatty liver if she does not eat, so I fed her some commercial food WITHOUT issues. That's when I came to this site to see if my situation was unique. Obviously not.

Vomiting and aversion

royalcanin.com

My cat has been on the diet for nearly 4 years since having a history of crystals and FIC. He's eaten this diet with no problems until approx 3 months ago when he started turning his nose up at it. The same happened with the SO wet food. I'm not sure if you changed the recipe or what but my cat refuses to eat it. I had to mix in some regular food to get him to eat which led us to a very costly vet visit with crystals forming again. Very disappointed

Change in formula? Very disappointed.

I have been buying this exact food for over a decade. I am a cat rescuer and well versed with cats and urinary blockages. I had a couple males on it and then eventually switched all of my cats over to it because they would devour this. Recently I noticed some of the cats throwing up after eating. I thought nothing of it aside from of they are too fast ECT. Well this has continued and my cats have lost weight. Now they refuse to eat this food. It now just sits there and gets thrown away in the morning when a new meal is served. I feed my cats in separate areas twice daily both wet and dry. The wet I feed is not urinary so.....I have multiple cats. When this issue is happening with all of them this is very concerning. I will be reaching out to everyone I can. Something is very wrong with this food. Please take this issue seriously before any other cats may be harned.

Something is different, cats are vomiting

Cats have been on for like a year or longer, we have the main cat that's the cause of going on this food start excessively licking his under belly around bladder/kidney area, our one cats now excessively licking her butt, vomiting not too bad mainly just with our other cat, oh and they've now got cat acne too(they've never had before) looking back at the ingredients(I did not buy the food) I would rather have my cats on friskies then I would this food, it's incredibly unhealthy, more so than friskies itself

Horrible horrible stuff

My cats have been eating this food for many years but all of a sudden they started boycotting it. I assumed it was a bad batch and bought a new bag. They enjoyed the new bag a little but still boycotting it. I noticed more  frequent vomits and then suddenly my cat had acute pancreatitis and was hospitalized for 7 days. The scariest ever! Nothing had changed for her in her environment just the behavior towards the food. My other cat also was boycotting the food but did not develop pancreatitis so I'm pretty certain the food was the culprit (they just had varying reactions to it - thankfully not both of them hospitalized). I immediately changed their food. I'm reading more reviews of pet parents noticing cat vomits and this is worrisome! Has Royal Canin acknowledged anything? Can you tell us what exactly changed in the formula? I'd like to make sure I don't feed her the new ingredients in any way to keep her healthy. This information would be helpful to all pet parents!

New bags made my cat sick and hospitalized

Cat always loved this, i have 2 cats, one which is not on this food, yet they used to fight over it. Now neither will touch it. The cat that was on it stopped eating it and has lost 10% of his body weight, vet can't find anything wrong with him and now we think it must be food. He literally would rather starve to death than eat it. When he does eat it he vomits. He started scavenging for food and will eat anything but this. He has been on it for 2 years plus. Not sure if there is a formula change?

Used to love it

My two adult cats have been eating this food without problems, until recently, since 2017. The most recent bag of food caused a myriad of problems for our two cats, that sadly took about a month and a half for us and the vet to diagnose. Both of our cats were throwing up almost EVERY TIME they ate. As a result, they were also eating less, which was concerning for our smaller cat, and clearly impacted their energy levels. Both our cats have other, differing health problems, so unfortunately it took us weeks to discover it was the food that caused their vomiting. Right after we switched to Hills, both cats stopped vomiting after every feeding, had appetite, and their spunk back. 

I feel terrible that they both suffered for about six weeks until we learned it was the food causing their sickness. Reading other reviews here and elsewhere online helped me diagnose the cause and I am astounded that RC has not had to report their formulation changes.

Vomiting

My cats have been on this food for two years without issue. Then, suddenly we get a bag in September 2025 and they are throwing up after EVERY MEAL. This went on for two weeks while we tried adjusting the amount, we talked to our vet, we took them in for blood work to rule out illness. They were perfectly healthy, but they were losing weight fast. So we realized the formula must've changed without any word. We changed them to the Purina pro plan and the vomiting stopped and they have now gained the weight back and are perfectly happy and healthy. So thank you Royal canin for the hundreds spent on vet bills and carpet cleaning as well as a month of extreme anxiety.

Formula change caused constant vomiting.

Have been feeding for years worked great until the most recent bag made all of my cats sick. Vomit, constipation, dehydration, days without eating any foods.  Thousands in vet bills to rule everything else out. Will not be going back after this.

Sick cats

I have five cats and when one of my cats, Simon, had a recurring UTI my vet recommended the Feline Urinary S/0 dry cat food. He has never eaten wet cat food, not because I haven't tried it, but because he dislikes it. I was worried he would not like it, but I was pleasantly surprised to see how much he enjoys it. He is not allowed to eat any other dry food because of his condition and thankfully this has him completely satisfied, my other cats love it as well! Thank-you for keeping Simon healthy. Not only is he free of UTI's, but he has also lost quite a bit of weight which he needed to do. Vicki Keehner
