Rated 5 out of 5 by Solved my female cat's bladder stone My petite black female cat was peeing blood- her urine was visibly red and she was peeing on the carpet. Got a digital xray done which clearly showed a pea sized stone in her bladder. My vet researched and saw that there are two types of stones and a 50/50 chance of which one it was. For one type of stone, the s/d food will actually *eliminate* the stone. I've been feeding her s/d canned now for a month and the symptoms are all gone, she is going in the litterbox again and I can see that it is not red anymore. She gobbles it up, too. I take her in a couple weeks for a follow up xray. So likely, she had the "right" kind of stone that this worked for. For the other type, I believe the c/d food can help, but they also could require surgery, too. I was very glad that this food seems to have made a significant difference, although the followup xray will tell for sure. Just had to share since this is a major *solvable* issue that many cats probably are punished or gotten rid of for what is a legitimate medical problem. November 16, 2014
Rated 5 out of 5 by Fast acting! Vet recommended! This worked really well for my patient! Was able to dissolve a struvite bladder stone in 4 weeks based on radiographs. My patient was notably more comfortable within a week and loved the taste per the owner! Will definitely try this in the future for suspected struvite bladder stones vs going straight to surgery!

Rated 4 out of 5 by Good product but pricey I am pleased with the results of this product. My cat seems to be doing much better. However when we switched to the dry food, although my cat likes the food, the price of the product was way more than I had anticipated. I understand that it is a prescription food, but at 18+ dollars a bag, i should think that the bag could be filled at least to almost the top. I was surprised at how much air there was in the bag compared to food. The bag is nearly half air. I will continue to buy this product at my veterinarians recommendation, and because my cat is sick, but for the price of the food, the quantity is lacking and I would be so pleased if the bag was at least 3/4 full. Thank you, -Pedro's Mom December 10, 2013
Rated 2 out of 5 by have to force feed cat to eat this My vet recommended this for two months. My cat ate c/d but wont eat this. No dry food only wet s/d. I work 12 hour shifts and had to force feed my cat to eat this . After being refrigerated trying to feed him the remainder of the can which is 5 x the price of friskies, . I feel like I'm torturing the cat shoving food down his throat and making a mess. I don't even know if this is effective. My cats UA didn't show stones but he is miserable when he has symptoms. So I'm willing to try this. I wish he could like the taste. November 26, 2014
Rated 5 out of 5 by It worked for my cat My cat has a laundry list of problems and does not empty his bladder well. At age 9 he began to have crystals in his urine. There was blood in his urine and occasional infections. He was quite uncomfortable and I was at a loss about what to do for him. The Vet bills were passing from the usual well into the thousands. His neurologist suggested Hills SD. It seemed to work overnight. Tim was no longer uncomfortable, and in a week the blood was gone from his urine. I have trouble complaining about the price when I think about the Vet bills I would have incurred. Thanks Hills! April 27, 2014
Rated 1 out of 5 by Cats don't eat pork - won't eat this product My cat was recently diagnosed with a bladder stone. The vet recommended s/d dissolution to try to dissolve it. It's main ingredients are pork - cats don't eat pork. My cat won't touch it, even when I mix only 1 tsp into a 6-oz can of his favorite regular food. Consequently, my cat has to have surgery. If you want to make a product that a cat will actually eat, PLEASE make it with fish or fowl. In addition, this product stinks to high heaven - my entire house stinks. April 1, 2014
Rated 3 out of 5 by my cat likes the food I actually don't know how to rate this product because the jury's still out. I won't know if this food dissolved the stones for another couple of weeks when a follow up exray is taken so I won't know any of the answers to your questions until then. All I can tell you right now is that my cat likes the food and is eating it fine. If the stones are gone then the product is well worthi the money. October 29, 2013
