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 5 out of 5 by Problems solved My vet recommend this cat food for my 8 year old male cat. He was having urinary problems (crystals found in bladder and urine, not being able to fully urinate, blood in urine) which could have been a huge problem if it wasn't for this food. After a few days of being on this food my cat is completely back to normal. He loves this food. I also have two other cats who are female and they also love the food. I had no trouble at all when I switched the food on them. I highly recommend this food. It's literally been a life saver. Also the auto shipping is on time and keeps me updated. I couldn't ask for more. July 20, 2016

Rated 5 out of 5 by Great Product My cat had Struvite Crystals in his urine and now has to be on a Urinary Diet. He has been doing great since he has been on it. I bought another well known Vet brand but my cat didn't like it. This food he loves and the food pieces are nice and big. July 17, 2016
