Hill's® Prescription Diet®
z/d® Feline Low Sensitivity

Adverse reaction to food

Food sensitivity and intolerance are potentially serious problems that can result in sensitive or irritated skin, coat and ear conditions or even gastrointestinal upset. Cats that have a food sensitivity or intolerance, also called adverse reactions to food, typically experience an abnormal response to the protein in the food. If your cat suffers from adverse reactions to food, it is even more important to feed the right food.

At Hill's, nutritionists and veterinarians have developed clinical nutrition especially formulated to help manage your cat's dietary sensitivity and help reduce the possibility of adverse reactions to food.

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 plastic bag out of the reach of pets and children.

Life Saver We have a two year-old kitten that, as it turns out, has a food allergy. At first we didn't know why she bit her fur and licked it raw. At one point her head was bald. The Dr. recommended ZD before we go to any other extremes. What a safe saver for our kitty. By the time we got her on the diet, she was not only bald, but was hairless with little rash-like bumps over her entire belly and very thin hair on the insides of her legs. After about 6 months on this diet hair covers her entire body (although still thin on the tummy and legs). But what makes this product extra special is that she actually enjoys the taste and consistency. She's put on weight, her fur where she has it is beautiful, and her licking and biting has been all but eliminated. Thanks so much for making such a good product. December 4, 2013
Cleared up my cat's itchy skin My calico cat has food sensitivities and scratches her face when she has ingested an allergen. Putting her on ZD has cleared up her skin! She and my male cat both eat the dry food, but neither of them will touch the canned food - apparently they taste different! It is a bit pricey for cat food, but worth it to know that my cat is healthy. September 26, 2013
Just What The Doctor Ordered Recently my cat Cleo became very sensitive to everything she ate, even the non-prescription sensitive system foods, as a result of a newly developed medical condition. She vomited multiple times a day and was losing weight fast. My vet and I reviewed several options and decided to go with Prescription Diet z/d. I am so glad we did. It has been a godsend. No more vomiting from day 2 (the other food had to clear her system)! She tolerates it well and ate it right away without the usual "change is bad" feline reaction. She is a much happier kitty, making me a happier pet parent. She doesn't need much a day because of the nutrient levels (make sure you feed only as much as the instructions tell you!), so a bag lasts a long time. This makes the food much more affordable than I had feared. On the Cleo scale, z/d gets 2 paws way up! August 14, 2013
Thank goodness ZD exists My senior male cat first believes that dry food is the only food that's worthwhile! And, he's had bouts of struvite crystals and suspected IBS. My vet called the Hills nutritionists and found that ZD could be a good approach to our issues. So far, so good! No crystals and his tummy seems better as well. I appreciate Hills' research into nutrition for all life stages and to address various health issues, and their willingness to work with vets and pet parents to ensure pet health. Thank you.

Its the only thing my cat can eat I have a highly sensitive cat about 3 yrs old, after months of shots cortisone we finally have him balanced but this is the only thing he can eat all other foods make him sick, since my one cat is on it, I put my other cat on it too. they both eat the same and they go through about 8 lbs a month, I don't like the smell of it but if they like it that is all that matters. I just wish is wasn't so darn expensive to buy, I have gone to the site online and printed some coupons and that helps a bit, but its just too high for my fixed income, I love my babies and have spent a fortune to keep them healthy.

Dry Z/d not appreciated by my cat My cat with tummy issues rarely touches the dry Z/d food. He enjoys the canned version and would probably eat more than a can a day if I could afford it. However, the dry food is rarely touched. I replace it frequently and notice that some is consumed on occasion, but certainly not daily. Is there something that can be done to jazz up the taste and still uphold the health aspect of the product? Thanks. Peg August 31, 2014
My cat loves this product! My cat loves the dry z/d! I have noticed a huge improvement in his appetite, and he has had no allergic reactions since I started him on this food! Before I put him on dry z/d, his allergies would cause him to constantly scratch himself to the point of bleeding. Also, other foods would actually cause an allergic reaction in and on his mouth. Dry z/d has allowed my cat to EAT, enjoy his food, and most importantly, LIVE! Thank you!! August 28, 2014
Stopped the vomiting My cat can only eat this dry food- she reverts to vomiting several times a day if she gets any other food. She seems to like it fine and I have been able to keep her happy and keep the weight she lost off (she needed to lose it). Only wish it was not so expensive!!!! August 16, 2014
