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

  • Feline Urinary SO is a complete and balanced diet for adult cats to aid in the nutritional management of calcium oxalate and struvite urolithiasis, recommended for cats at risk of developing lower urinary tract disease
  • Provides nutrition that aids in the management of pure struvite uroliths.
  • Royal Canin Urinary SO Index® promotes a urinary environment unfavorable to the development of both struvite and calcium oxalate crystals
  • Increasing the urine volume simultaneously reduces the saturation of urine with calcium oxalate and struvite crystals
  • 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

Note: Royal Canin Veterinary Diets require a veterinary prescription. This product will not be shipped until a copy of a valid prescription authorization is faxed to 1-800-619-7973 or e-mailed to rx@chewy.com.

  • Easy switch, but not great ingredients

    My 4-year-old Samson recently had surgery to remove a bladder stone, so my vet prescribed him this food as well as the canned Urinary SO food. My family cat had similar issues years ago and once he was on this diet, there were no more urinary problems! I am hoping this does the same for my Sam cat. I was previously feeding him Wellness Core which I liked due to it's high quality ingredients (grain-free, no byproducts). I was disappointed that the first ingredient in this food is pork byproduct. For an expensive prescription diet, I was hoping for better ingredients. But, whatever I need to do to keep the crystals/stones from coming back!

The upside about this food is that Sam gobbled it up immediately without a gradual change over (which my vet said I shouldn't do since he should only be eating this food now). Also, I want to say what an amazing company Chewy is. Not only are they saving me money on this food and making it more convenient for me by delivering it to my doorstep, the whole process of getting the prescription approved was so easy and personal. The company was on top of everything, calling me to explain the process! It makes me feel like they really care about my cat. Also, I love the hand-written holiday cards! … more

  • Cats loved it

    My cats have eaten the Science Diet version of this for going on 13 years. I tried switching at one point to purina's urinary formula and one cat hated it so much he'd eat the dog's food instead. I was a little hesitant in trying new food but the cost savings was appealing and royal canin seemed to be viewed as the superior brand to SD. Cats loved it and were enthusiastic about trying something new for the first time in over a decade.

  • Great product; even better customer service!

    By on

    My cat has suffered with multiple UTIs and my vet prescribed her the Royal Canin Urinary SO dry cat food. This particular food makes my cat drink more which helps to keep her hydrated and flush her system out more regularly so that it reduces the possibility of calcium and crystals to form which contributes to the UTI and discomfort. This food has helped keep her healthy and both of us happy!

    After I had reordered the food I had been using for my cat, my vet changed his food. I hadn't received the order yet, so I was told to refuse the order, it would get sent back and they would refund my money. On the same call, the Rep. placed the order for this new prescription diet. There was no hassle and my money was refunded that day even though it took a week and a half for the food to get back to them. Also, my cat seems to enjoy the new food.

  • Cats LOVE this food

    By on

    We had to switch our cats to a urinary health-based diet and they simply love this dry food. Pretty sure they lick the bowl clean every day. We used to buy Wellness and there was always food left in the bowl until the next time they were fed...not anymore! Royal Canin is costly but we're ok with that knowing the quality level is far and above anything else.

  • Great Rx food and quick reliable service

    By on

    Royal Canin makes a great product, my cat loves the taste, it's a relief to have this food available on Chewy, because it's more economical for me and I won't have to worry about my cat having issues with crystals in her urine as long as she's on this food. Delivery was easy and quick. And I appreciate that they took care of contacting my vet for the prescription.

    I was worried to switch foods after my male cat had a urinary block. He is a picky eater and has always preferred dry food (which is likely what caused the block). He liked this food immediately! I also recommend the canned food (morsles in gravy). He loves that too and is definitely getting more water in his diet!

  • Alllllll the kitties love it!

    By on

    After one kitty had issues with stones, we switched them all to this food. They adore it! Literally out of the bag they were gobbling it up and not having any GI issues. The food pricey to sustain 6 cats but we knew that it was really the way to ensure the kitty with the stone issue would hopefully not repeat. He will NOT touch wet food which is the ideal diet for cats; especially those with urinary stones. The bag has a fantastic reclosable system that acccctuuuuaaaaally works unlike most. It comes super vacupacked and was extremely fresh. Chewy is the most reasonably priced source thus far and free shipping is awesome!!!

  • wonderful service

    By on

    I have been using the Urinary SO for my 3 cats for years as my older one gets urinary issues. Chewy called my Vet, got a prescription for the Urinary SO formula and had the bag to my front door in 2 days of my order which was pretty impressive. And even better it is at least 30% less expensive that purchasing at the Vet office. I signed up for the monthly subscription and am so very happy I did. Not only do I not have to go and wait in line at the Vet's office, but I also save a lot of $$. Thanks!!

    Outstanding customer service. It is so easy to order and I couldn't believe how quickly I received my order. This is the first time I am trying automatic delivery and I am hoping it works out for me. I am bit concerned it may be a bit too early, but I will have to wait and see. Thank you for being as wonderful as you are!
