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, or if you are feeding Prescription Diet i/d Feline Gastrointestinal Health to a kitten, 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.
  • Split the recommended daily amount into smaller portions and feed throughout the day.
  • Keep fresh water available at all times!
  • For best results, have your veterinarian monitor your cat's condition.
  • To prevent suffocation, keep this plastic bag out of the reach of pets and children.

I/D Prescription Wet & Dry Cat Food My Cats eat the dry and seem to like it. No more Diarrhea from my Male Cat. So it works. Female put on weight since she is eating this as well. She is Overweight. The wet must not taste very good. Both cats don't like & I Have to mix it with other canned food. If you leave the food sitting for a couple of hours, it turns rock hard & looks like it has been sitting out for days. July 31, 2014
Saved my cat's life My 12 year old cat, Mr. Bear, had severe GI issues. He went from a 13 pound cat to a 7 pound cat. I thought he was going to die. But my vet recommended putting him on i/d. I had tried him on other sensitive stomach foods that were over the counter, so I was skeptical. But i/d was the cure! All of his vomiting and diarrhea stopped. He gained back all of his weight. And lived another 7 wonderful years. I couldn't be happier with this product or will Hill's. December 19, 2013
Great choice My 11 month old Maine coon kitty suffered from bouts of diarrhea off and on for months. My vet recommend prescription diet ID for gastrointestinal health and it has worked wonderfully. My kitty hasn't had an incident since starting this product. Life is much better and Baby is much happier. She loves how it tastes and I love how it works. I would recommend this product to someone who's cat has irregularity. November 7, 2013
Rocky's story I adopted a 7 month old kitten from a pet store in 2010. We named him Rocky. However, when Rocky was 2 years old, he suddenly started vomiting frequently and he passed a lot of gas. We took him to the vet and they diagnosed him with a wheat allergy and put him on an expensive food that could only be found in specialty pet food stores and at the vets office. It seemed to help for awhile, his vomiting and flatulence became less frequent. Shortly after Rocky's 4th birthday, we adopted another cat- a 6 month old kitten named Reginald. However, shortly after we brought Reginald home, Rocky started having off and on diarrhea. He was also quite lethargic. We brought a stool sample into the vets office and he was tested for parasites. The test came back negative. We decided to just wait to see if it went away on its own. he would have a few good days, but his diarrhea would always return within a few days. He also had 3 "accidents" which was very unusual for him. He had never had an accident before. After 2 and 1/2 months, his diarrhea had not gone away completely, so we put him on an antibiotic the vet prescribed, the antibiotic had no effect. We brought him into the vet again. The vet examined Rocky and ordered a blood draw and another stool test. He again tested negative for parasites and his bloodwork came back normal. The vet decided to put him on Hills id- what a difference! We discovered that along with being allergic to wheat, he was also allergic to canola oil (which was in his previous dry food), his diarrhea went away for good! Rocky is a picky eater and would turn up his nose at many dry foods we tried with him, but he loved Hills id! Rocky is now 5 years old. He has not had any diarrhea since the incident I described (almost a year ago). He never passes gas anymore. He isn't as energetic as Reginald (who is now a year and a half old) but isn't so lathargic. He vomits occasionally, but not as much as he used to. Rocky will likely need to be on this wheat-free, canola oil-free diet all his life, but that's okay, because as of right now he is doing well and is living a healthy life. We hope that Rocky lives a long life and stays healthy! Thank you, hills id!! Here's a picture of Rocky! September 14, 2014
serious diarrhea My vet recommended this for a serious, foul smelliing diarrhea problem and within two days the stool had taken shape and was no longer an on-going problem. The kitty is not nuts about this stuff but she eats it and has gained weight. The price is high for me but I will cut back in other places for the health of my little friend October 18, 2014
Works great for cat with sensitive GI areas! My long hair domestic cat...actually super long hair must have some Persian in him, had very bad furballs that he ended up having surgery to remove several that were hard as rocks and stuck in his GI tract. Afterwards the vet put him on Prescription I/D. I didn't think this would be a forever deal!! But anytime I take him off of it or mix it with other dry food, he ends up rushed back into the vet for at least an overnight stay while he gets re-hydrated and better. After thousands of dollars in vet fees, he's permanently on Prescription i/d. Only issue I have with the Prescription brand is that it is only sold at vets. Couldn't we have it at specialty pet food stores with a prescription or similar? I must have spend over $2K just on pet food in the last 6 to 8 years. Now 14 years old, our "free kitten" now up to the $6K free cat! I think he's done pretty good for such a sick guy in the first place! August 15, 2013
Needs it but does not like it My cat has a sensitive stomach ever since I found him as a kitten under my neighbors porch. I tried feeding him regular cat food but he kept throwing up. I took him to the vet and was given a prescription for Hill's® Prescription Diet® i/d® Feline Gastrointestinal Health. He does not throw up any more but he does not like the taste. I have to mix the Hill's® Prescription Diet® i/d® Feline Gastrointestinal Health with other Hill's dry or wet cat food so that he will eat the Hill's® Prescription Diet® i/d® Feline Gastrointestinal Health. I wish Hill's would change the formula of Hill's® Prescription Diet® i/d® Feline Gastrointestinal Health so that cats would like the taste. June 30, 2013
I/D formula is helping Sherman my outdoor cat! I have 5 cats outside and 5 inside. My inside cats eat W/D and are doing fine. However, one of my outdoor cats, Sherman has been having stomach issues. My vet recommended I/D dry/wet. He doesn't care for the wet, but seemed to have taken to the dry for over a month. He fortunately has gained 1/2lb from the 4lbs he had lost. I hope he continues to eat this food as its formulated for cats with IBS, gastic problems. I might switch all 5 outdoor cats to this food this way, he won't be tempted to eat their food, plus most of them are older cats so the I/D will be good for them as well to eliminate vomiting, etc. Thanks again Hills for keeping my cats healthy!
