Feeding Guide

Daily Feeding Guide:

Important Feeding Information

  • These amounts are a starting point only. Your cat may need less or more food to maintain proper weight. Adjust as needed. If you are unsure, ask your veterinarian.
  • With your veterinarian's approval, mix increasing amounts of your cat's new food with decreasing amounts of the old food over a 7-day period. Prescription Diet formulas are available in a wide variety of dry foods and treats for your cat's unique needs, and canned foods with delicious flavors your cat will love. Supplementation with other foods or treats is unnecessary and may decrease the effectiveness of the food. When using with canned food and treats, decrease the amount of dry food to avoid overfeeding.
  • Keep fresh water available at all times!
  • For best results, have your veterinarian monitor your cat's condition.
  • To prevent suffocation, keep this package out of the reach of pets and children.

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.

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
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
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
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. May 29, 2013
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
Wonderful For Cats with Food Allergies I started my cat who has very bad food allergies (skin). The Dr. started him out on the Z/D but it gave me very bad diarrhea. The D/D cleared the diarrhea up in 2 days. His allergy seemed to have cleared up quickly also. One problem, it has made him and my other cat constipated. January 13, 2014
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.
