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
  • Provides nutrition that aids in the management of pure struvite uroliths
  • Relative Super Saturation (RSS) methodology predicts the crystallization potential of urine; RSS is used to develop diets that lower the concentration of ions contributing to struvite and calcium oxalate urolithiasis
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals
  • Reduced level of magnesium, a natural component of struvite stones

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
Max approves Max loves his new food. He has a tendency to get crystals in the urine and this prevents them. November 5, 2013
Saved my Rideo My boy, Ridley, suffers from Feline Lower Urinary Tract Disease (FLUTD). He was eating a different recommended brand and developed crystals again, resulting in an ER visit and hospital stay. This food switch seems to have saved him, though it has also spoiled him. He wants it ALL THE TIME!!! March 6, 2014
No more trouble with wet food Our cat had to have several teeth removed and was having trouble transitioning from dry to wet food. He hated (as in would rather starve than eat) both the Hill's Science Diet Urinary wet and the normal larger cans of the Royal Canin Urinary SO wet. However, he LOVES these morsels and gravy cans. And an added bonus, they smell much less like rotting insides than the classic wet. We have tried both the normal and moderate calorie, but we stuck with the moderate because he's a little hefty (~18 lbs.). They really have been the perfect find (purrfect?). February 19, 2014
So far so good My kitties both eat SO kibble, but now they eat the moderate-calorie morsels several times a week, as well. They seem to like this product better than all other urinary canned food I've tried. I'm delighted, and so are they (-: February 18, 2014
My fussy cats eat it. My veterinarian suggested I try this cat formula for my cat that can develop struvite crystals in her bladder. She had already rejected Hill's RX diet formula with low calcium, phosphorus and magnesium levels and I was concerned that this formula would be left untouched in her feeding dish as well. Chewy delivered my order promptly. My cat ate this food! The higher calorie version was accepted as well. February 15, 2014
