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
  • 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

Rated 4.8 out of 5 by 550 reviewers.
Rated 5 out of 5 by Fast and Easy! With my coupon I saved almost $20 and didn't have to go to the vet during business hours, which is tough for a working fur-parent. Shipping was quick and gave good updates so the food wasn't sitting in the heat all day. I will definitely be using chewy again! August 21, 2016
Rated 5 out of 5 by Great Experience! Using could not have been easier. Usually I have to drive 30 minutes to the closest PetSmart to get my cat's prescription food. Our vet closes too early to get it there. Finding that sells this food was a life-changer! I no longer have to drive to get it, it's delivered right to my door in 2 days! And it's cheaper than PetSmart / the vet as well! August 22, 2016
Rated 5 out of 5 by So happy about this My cat was just recently prescribed a special prescription diet for urinary track health. I have tried similar products but the wet canned version & my kitty was not interested in it. She will eat this which has really relieved my anxiety over the new diet situation. August 19, 2016
Rated 5 out of 5 by Wonderful Product and Company This food has drastically improved my 2 cats lives and was the right switch. Chewy is an incredible company and I will continue to buy my cats and dog's food from them. They are easy to work with, have great customer service and fantastic values. August 18, 2016
Rated 5 out of 5 by Finally a dry food he will eat! Our cat had a very serious case of crystals in his bladder and was put on a prescription diet. We can usually feed him canned food but there are times when he just has to eat dry food while we are away. Spent lots of $ on the dry food originally prescribed and he hated it no matter what. If we put it with canned food and let it sit he would sometimes eat it. Called the vet for other recommendations. She gave me samples of the Royal Canin Vet diet dry and canned. What a difference. He loves both of them and no longer wants to eat the "other brand" canned food either. We have to mix it with the Royal Canin. August 5, 2016
Rated 4 out of 5 by This is a good dry food for my 2 Siamese. Our 2 Siamese had to go on a prescription dry food and this Royal Canin Urinary SO was prescribed. My cats do like it and this large bag was much cheaper to purchase than if I got it at the vets. The mail order came quickly. August 19, 2016
Rated 5 out of 5 by Great product Very easy to use this website! We will use this again. August 21, 2016
Rated 5 out of 5 by Great Product Our three cats took to this dry food very quickly. We didn't have to switch them over incrementally. They definitely enjoy this dry food at meal time and we also use it in the treat container. August 16, 2016
