Pets can be sensitive to sudden changes in their diets. For this reason, it is extremely important to follow a gradual transition plan to best support your pet's health and product effectiveness. It is recommended to follow at least a 7-day transition plan before exclusively feeding your pet a new food. Cats will often refuse mixed diets, so we recommend adding the new food to a separate bowl from the old food. Start by mixing 75% of your pet's current diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the current diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the current diet with 75% of the new diet. On Day 7, you can feed your pet the new food exclusively. Ask your Veterinarian about the best way to transition your pet to a new food.

Is there a hills s/d wet food?
Answer by Jenny • Jul 05, 2022
Yes search this site
Is there a larger size?
What is the difference between S/D and C/D?
Answer by • May 11, 2019
Hill's Prescription c/d Multicare is intended to treat the various different sources that a urinary issue stems from, such as struvite crystals, calcium oxalate, and Feline Idiopathic Cystitis, and can be fed for the entirety of a cat's lifetime. Hill's Prescription s/d is only intended to be fed temporarily, and is honed-in on treating urinary issues caused my struvite crystals.
Yes, I'm wondering why the manufacturer doesn't offer this diet in a larger bag. The 4# doesn't really last but a little more than a week-long even alternating with the cans. My kitty will need to remain on this diet for the rest of his life.
Answer by • Apr 02, 2018
At this time, Hill's Prescription Diet s/d Urinary Care is only available in a 4 pound bag.
unfortunately, my cat is not liking this particular food. I need to write Hills about making us buy 24 cans at a time.

Product is EH
My cat won't eat this food unless its mixed with wet food. Don't know why though. My issue is that the cat food I received wasn't stored correctly. The ingredients separated because it got too hot. The food is bad & my cat is HUNGRY! High price for a little amount of food that my cat can't even eat. Way to go!

Dissolved Bladder Stones!
I took my cat the the vet for what I assumed was a UTI. I have the wonderful litter box with the diapers in the bottom tray, so I can tell if my cat is having urinary issues. The vet took an ultrasound (or something) and showed me the photos of the little stones in her bladder. He said surgery would be needed to remove them unless Hills S/D special food dissolved them first. He gave me a prescriptions and told me where to buy it (it was a Saturday). I called the store and they did NOT have it. I reached out to Chewy on a chat and they said I could upload a photo of the prescription. I had the food a few days later and the blood has disappeared in less than two weeks. My cat is VERY picky (won’t eat turna or shrimp or chicken, etc.), but she narfed down Hills S/D! Her urine seemed normal (no blood) after only 10 days! The vet will take another sonogram in about two weeks to see if the bladder stones are indeed gone. Chewy has the products and the great customer support staff that my cat and I need. Thank you!!

Happy with results
On the 14th day, I finally saw a full day of litter box deposits with no hint of blood in my kitty's urine. It's now been 18 days on this prescription food and things finally are staying normal. I had my doubts but also high hopes.
Very satisfied with results and hope the next urine test at the vets goes as well as things look.

It works! We need a bigger bag.
This worked for my cat. I wish it was less expensive and came in a bigger bag. Thanks to Chewy for getting this to me quickly when the vet dropped the ball on faxing you the authorization!

Reduced my cats stones
Delivered quickly. My cat wouldn’t eat it at first but I mixed it with her food and when she got used to that I fed her 100% prescription food. Vet said she can’t feel any stones at the 2 week checkup.

My cats didn't care for it
One of my cats has issues with crystals forming in his bladder and has put on this food. Neither of my cats cared to eat this after their first serving.
