Rated 5 out of 5 by from 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 from 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!

Rated 5 out of 5 by from This is a high quality product that has kept our cat from having extreme digestive problems! Our cat had extreme digestive problems being on another cat food brand for years. Our vet recommended the D/D duck and green pea, and she immediately returned to normal health. While it does cost more than most cat foods, we appreciate the fact that our cat has a better quality of life. The periodic coupons help with the cost! Thank you!

Rated 5 out of 5 by from Only thing my baby can eat I had trouble for yrs my cat would hold food down . The vet said to try this and she's been eating it for about 2 yrs now. She still has some skin issues but I guess it's just her. She loves the taste and I feel good about feeding it to her. It's pricey but she is worth it.

Rated 5 out of 5 by from 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 from 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 from 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!

Rated 5 out of 5 by from satisfied This product was recommended by our vet and purchased there. Our cat likes the food and it took care of her problem. I would also like to say that I had problems printing an online coupon- I contacted the coupon center and I received a coupon in the mail within several days. Thank you for a great product and great customer support!
