Royal Canin Veterinary Diet Urinary SO Moderate Calorie Morsels in Gravy Canned Cat Food

Lower urinary tract disease (LUTD) refers to a group of disorders that commonly leads to irritation of the urinary tract and corresponding undesirable clinical signs.

What causes Lower Urinary Tract Disease? In cats, bacterial infections are far less common. Urinary crystals and stones are often linked to this disease. The most common cause of Lower Urinary Tract Disease in cats is idiopathic cystitis. This diet promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals.

Key Benefits

  • Recommended for Cats at risk of developing lower urinary tract disease and who are predisposed to weight gain
  • Moderate calorie content, helps maintain ideal weight
  • Dissolution of pure struvite uroliths
  • Help prevent struvite, calcium oxalate and phosphate uroliths

Max approves Max loves his new food. He has a tendency to get crystals in the urine and this prevents them. November 5, 2013
My cat loves it. My cat is alive today because of the 'Urinary SO' formula. He had chronic UTI's and blockage. After expensive treatment and PU surgery to prevent his death, he was blocked again. The Vet treated him once again and sent me home with this food for my cat. He loves it!! Even though it is a little pricey, it's worth it to me to keep my friend healthy. I feed him wet in conjunction with dry food for the crunchy aspect. My cat hasn't had anymore problems and is back to playing with my dogs. August 11, 2013
My cats love it. It is pricey but one of my cats was having problems. All three of them love it! February 18, 2013
Have cat with history of urinary track disease. Been using for years. Little expensive but my willing to pay for my baby. Fully packed can, no waste. So glad they came up with moderate calorie as my cat is on the heavy side. January 18, 2013
My cat loves this food! My cat has been eating the wet and dry food for a while now and loves it! He has not had a problem with his urinary tract since he's been eating this food. June 13, 2014
Morsels are the best, says Copper the Cat Royal Canin Veterinary Diet Urinary SO Moderate Calorie Morsels in Gravy Canned Cat Food is the ONLY food my cat will eat. He loves the morsels and won't touch the pate. The shipping was very quick!! July 19, 2014
My cat likes this SO version as well as the "non-diet" formula. My Petey's been on the regular SO formula since he developed calcium oxalate crystals, and he's loved the food. Recently he had an IBS episode, so his vet wanted to reduce the fat in his diet and we changed over to the Moderate Calorie formula. I wasn't sure Pete would like it as well as the original SO formula, but he does. Royal Canin folk have figured out how to make cats with health issues happy with their food. July 10, 2014
This food was highly recommended by my vet When my beautiful male took ill, I immediately called my vet. She is wonderful, and was quick to determine his problem after a thorough examination and testing of his urine. Sure enough...he had crystals. :-( She reassured me that we had some options that would head us in the right direction to battling this difficult situation. Her own little guy once suffered from having crystals also, so she was able, through experience, to inform me that after using this food for 6 years, he had not relapsed. She explained the importance of being vigilant in observing my fellow for any signs of reoccurrence in terms of symptoms; taking a long time to urinate - along with hardly any urine being eliminated as a result. Basically all the things I had noticed when I realized that something just wasn't right with him. So, with her guidance and ability to provide me with the knowledge I needed to move forward with the Royal Canin Veterinary Diet SO Moderate Calorie Morsels in Gravy Canned Cat Food, I began feeding the new food immediately. My little guy instantly took to these tasty morsels. ( Was I ever thankful for that ! ) After a few days and conferring further with my vet, we also opted to add some chondroitin to his food to help smooth / coat the way as the urine took its path during elimination. The food is a hit with my handsome guy, and he seems to have received a new lease on life. I do time his visits whenever I can , just to make sure he's relieving himself within a reasonable time frame - and he's doing so well ! We also are feeding in conjunction with the canned food, the Royal Canin Urinary SO Moderate Calorie Dry Food for their random-at-will enjoyment and good health. All three of my triplets love this food...and I'm actually happy that they do - as feeding the dry food to the others can only be helpful to them in terms of hopefully deterring the possibility of the development of crystals in them ! As Benjamin Franklin said: "An ounce of prevention is worth a pound of cure. " I , along with my vet and my triplets, agree ! "Three Cheers" and "three sets of Whiskers Up" to Royal Canin, for producing food products that can help so many beloved cats and dogs overcome what is a most uncomfortable and, if left untreated, potentially lethal health issue.
