    Cat urinary formula by Philip from south daytona, FL01/05/2013

    Excellent product. cats seem to like and no reoccurences of urinary issues

    Urinary SO Royal Canin by Nancy from Clinton, MD04/01/2013

    It is good that one can order this product online if your cat has to eat this food for its urinary problems. It is a better price and you can get it sent directly to your house, saving you a trip to the vet. My vet is far away so it is wonderful to be able to get this shipped to my home.

    by from 04/19/2011

    Shipping is not free for pet food. The shipping, if the price is above 85.00, it is less. However, it is not calculated in the online invoice order. You need to check the table for shipping cost( check shipping page ) and then call them to correct this charges appropriately.

    and by they from changedI


    great service by taz10/28/2011

    i thank you for your continuing service as i have 2 male cats , one which is a large cat at 30 lbs and not fat just large to the point he scares people but is extremly docile but has to have this food due to problems with urinary tract problems.without it. thank you very much

    Great product by Tree from Luxemburg, Wi06/26/2013

    Excellent food for my older cat with a history of urinary infections. Would much rather preventive special cat food than weekend emergency vet visits. Plus the added stress on him was harmful to him. He also prefers this over other cat foods when both are put out.

    Keeps them Happy by MRam01/25/2013

    My boys r always happy to get there meal and the Royal Canin Urinary cat food keeps them both happy and healthy. Excellent!!

    Worth the price by Heather08/20/2008

    This food works perfectly. It has saved me hundreds of dollars in vet bills and has saved my cats a lot of pain! Urinary problems in cats can be potentially life threatening and since I started using this food we've had no problems! I have tried other brands and they don't work anywhere near this well and my cats LOVE the taste.

    Great food by Rae from Colorado04/12/2013

    Our baby has a very sensitive stomach and we tried everything, even science diet but this was the only food that kept her belly calm.

    Has saved my kitty by Stephanie11/24/2009

    My cat had multiple episodes of bladder stones last year that nearly killed him. After thousands of dollars in vet bills, the vet expected that he would continue to have these problems and recommended some pretty radical surgical options. The vet suggested this food as a last ditch effort. Knock on wood-we haven't had a single problem in a years time on this diet (no extra snacks on the side). It doesn't smell great and gives the cat similar breath, but he is happy and healthy now, and of course, that's all I care about.

    Excellent diet for cat with kidney issues by KF01/18/2012

    My cat (who had surgery for urinary blockage) has been on this diet for two years without problems. He has a shiny coat, good energy, and eats this food without complaint.

    fast shipping by Grand from Richmond, BC11/15/2012

    my cat has diarrhoea problem, my vet gave him medicine and probiotic and it got a little improvement. my friend told me her cat has the same problem n her vet suggested this product n it works well. so i try, not even finish the first bag i can see the difference, good product!

    Good Price by bdee11/06/2012

    We like this food, and this is the best price we've found!

    Excellent product by Graycats from Florida10/23/2012

    My vet recommended this food after one of my cats had a UTI. That was a few years ago now and I continue to use this food for all my cats. They love it and it keeps them healthy. It's a little more costly than some cat foods, but when you consider your pet's health, I'd rather be safe than sorry. I'm on auto-delivery with EntirelyPets and have had great service. I'd recommend them highly.

    ROYAL CANIN IVD by Trish04/17/2013

    The vet prescribed this cat food and it really helped my cat, Dobby. He is now back to his normal weight and feeling good again.

    Exactly what I needed! by Lyudmila from Brooklyn, NY02/15/2012

    Excellent, Can't ask for more. This is exactly what my vet prescribed for Nika. She is happy and I am happy! Thank you! P.S. it is a bit cheaper than I was buying from my vet!

    by catherine from Ocean View, DE12/01/2011

    customer service is terrible. Have been waiting 2 weeks for product. Have not received anything...can not get in touch with customer service either via chat or phone!

    reasonable price by max from NC06/19/2013

    Great product by shabrit11/19/2011

    Two of my cats have urinary issues. This food works wonderfully.

    Royal Canin Feline SO by KWill800 from Venice, Florida12/03/2011

    Best dry catfood for cats with urinary problems

    My finicky cat loves this food by Phil from Orlando FL04/24/2012

    My cat Princess normally turns her nose up at the specialty food I buy her, which is a problem because she needs food for a cat prone to UTIs. But she loves the Royal Canin IVD Veterinary Diet Urinary SO dry food, so if she had thumbs she would give it four thumbs up.
