Rated 4.8 out of 5 by 21 reviewers.
Rated 5 out of 5 by Excellent Food for Cats w/Food Allergies My cat Augustus whom has very bad food allergies, especially chicken, is doing great on this food. His coat is beautiful, he is his normal self, and he loves the flavor. I also feed my other cat Temperance this food because it is a complete balance and once she smelled it, she didn't want her other food. One Precaution: Watch your cat's weight. Very Fattening.

Rated 5 out of 5 by Overall a great product My cats ( 2) have been on D/D dry for about 3 years. I also fostered a cat this summer and she had no GI issues switching to a higher quality food. She readily accepted the new diet and I could really see the change in her appearance. Her coat and skin were less dry, she gained much needed weight without getting too overweight. My own cats don't seem to be bothered by static in their coats during the dry winters. With 2 cats the cost per day is pretty minimal and the 8.5# bag last me about 1 month. I know several pet owners who use the D/D diet and have been very happy with the product. Best part of a high quality diet is that the stools are small and no odor!! January 3, 2014
Rated 5 out of 5 by Cat looks incredible I thought I had my cats on a quality food. My vet recommending switching to prescription diet for an allergy issue. After about 3 months on their new diet. There is a stunning difference in their appearance. Their coats are full and glossy. My older cat looks years younger. It has been an absolute transformation. I recommend this food to every pet owner I know. The attached picture is of my 15 1/2 year old cat, Puss. She has never looked better. I think of this food as an investment in her long term health.

Rated 5 out of 5 by great product, but goes STALE with new bag Our 4 cats have been eating d/d for about 2-3 years now. It's worked well at curbing vomiting & diarrhea due to their allergies. I was very disappointed to see the bag is no longer resealable. I thought the last bag as just a fluke and dumped it into an older bag that still had the zipper seal. Nope, this latest bag bag has no seal either. Our cats love the food, but don't like it once it's been sitting open for extended periods of time. Hill's, PLEASE BRING BACK THE RESEALABLE BAGS.

Rated 5 out of 5 by All 3 of my kitties LOVE this dry food!!! Although Hill's Prescription Diet d/d Dry Feline Formula is prescribed, all 3 of my kitties LOVE the Duck & Green Pea Formula. Two of them are 16 year old brothers & the other is a 4 year old little girl. They also like the canned wet in the same flavor & the Venison. It's important to me to be able to have a HEALTHY food that not only is safe but they really enjoy eating. Thank you so very much! July 9, 2015
Rated 1 out of 5 by Tried but no luck I have heard a lot of people complain that their cats would not eat the D/d. I did not think anything of it until a vet prescribed it for my own cat (who eats anything). I tried the venison first and the cat wouldn't even go near the food bowl with it in there. After a few days of him not eating I switched it out for the Duck. Still no luck. I had to put him back on his normal food. It is way too expensive and not at all palatable. May 19, 2015
Rated 5 out of 5 by What a change this made for this kitty! Recommended to an owner with a kitty for chronic diarrhea and vomiting. Worked perfectly! The owner decided to try a different food (otc novel protein) and within weeks back to the same issues; vomiting, diarrhea, and now also urinary issues. Returned to Hill's Rx D/D Duck and Green Pea and wow, back to normal again. This little kitty is happy and healthy again! May 20, 2015
Rated 5 out of 5 by really made a difference My cat was scratching all the time and actually made wounds and open sores. After a few weeks of the Duck/Pea food he was back to normal. I mistakenly assumed I could re-introduce a store bought food, and he immediately went back to scratching and itching. We are now on the Duck/Pea for life. Nothing else would be worth it. He is happy and health. Thank you. December 15, 2014
