Product Description

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 Urinary SO saved Lucky Boy's life! back on July 4, 2013 my cat Lucky Boy had to be taken to Pet Emergency because he was in extreme pain and I did not know why! A few minutes past midnight the Vet came out into the waiting room and said they had to do emergency surgery because his urinary tract was completely blocked and his kidneys were failing. It was a "hail mary" surgery because he lived! After many days of losing sleep while speaking with many vets and friends and finally got to speak with a Royal Canin Rep (Jodie) - I got all my answers and my heart and mind were put at ease. I put both my boys on Royal Canin Urinary SO "Dry" and "Wet" - they prefer Morsels in Gravy. Lucky Boy is doing great and no scary return visits to the vet! This is his "second" life he's used up. He's a rescue kitty from a cemetery where my brother works. My brother is in charge of all the landscaping and 20-years ago started a ministry to rescue feral kitties and find them homes and he still does this ministry today! Lucky Boy was found 3-years ago in a pile of rubble and his siblings were all dead except for him. That is why he is called "Lucky Boy" - He is a blessing in our lives! March 19, 2014
Rated 5 out of 5 by both my cats love it. good food, but very pricey. although I am beginning to think that all these so-called premium prescription diets are garbage, this one at least has animal proteins as 3 out of the first five ingredients. Hills first ingredient is grain. Seems like they take out the stuff that causes urinary problems, but leave a product that is no better than the really cheap supermarket foods - at 4 times the cost. oh well, it appears to be working, and I am mixing it with the SO canned food. if you want to stop urinary problems, feed them canned food exclusively or with the SO dry. I also add water to the dry. so far, my strategy is working. October 30, 2013
Rated 5 out of 5 by My cats love this! My cats love this food that they need to prevent bladder stones. Initially, they would not eat the gel/pate variety and would only eat the morsels in gravy. June 28, 2012
Rated 5 out of 5 by Cat loves this My cats world was turned upside down a couple months ago. Food as he knew it was no longer right for him. The vet put him on this, & the dry form a well, and he is still happy & big! TY for these products, (just wish they didn't cost soooo much!). July 25, 2013
Rated 5 out of 5 by Helps prevent urinary blockage My kitty required 2 trips to the emergency vets to clear first a urinary tract infection, and then even worse blockage of the urethra by a stone. So far he has been just fine and dandy and has put back the weight he lost during his last hospitalization. He is a picky guy, but he eats this food well. I think that this may be the answer to his problem. Thank you for helping my boy November 6, 2013
Rated 5 out of 5 by low cal cat food and cat loves it!! Vet put my overweight Tabby on this due to blockages and he loves it! Tried another prescript. food and he liked it, but he gained a lot of weight on it. This low cal food IS more expensive, but I've learned, it's worth it. Went off it to save a few bucks, but had a scare and I'm right back where I started. IF your cat is on this, don't cheap out like me and try to find something else. This works and is worth every penny when it comes down to it. BTW, my Tabby is healthy, happy and has lost weight! July 21, 2013
Rated 5 out of 5 What the doctor ordered. After 2 overnight stays at the vet ($$$$) for crystals we started our cat on Royal Canin. It seems to be doing the trick and after a few finicky days he gobbles it down. Mr. Chewy was easy to work with. Cheaper than most and free shipping. Works for me. July 3, 2012
Rated 5 out of 5 by Loves it better than his Fancy Feast! Just started with the urinary problems in my 4 year old male. Got the pate from my vet and he wouldn't eat it. I ordered the morsels in gravy and he loves it. Doesn't even bother with the Fancy Feast I fed him all his life and still feed my 2 females. is great - fast ship and good customer service.
