Cat Diseases - Allergy and Food Intolerance | Hill's Pet

A diet trial lasts 12 weeks, in which the cat is fed only the test food; no treats, no flavored medicines, toothpaste, or supplements — no exceptions. Just one diet slip-up (such as giving a treat containing an allergen) could invalidate the entire trial and you will have to start over.

Elimination diets are the best way to diagnose a food allergy inyour cat since laboratory tests are not as accurate in making adiagnosis.

The main diagnostic method for a possible food allergy is to change your cat’s diet. There are many types of diets available, but your veterinarian will recommend one that contains ingredients not already in your cat’s current diet. This can be a protein change, such as changing from chicken or fish to rabbit or duck. It could also be a grain, corn, or soy free diet, a homemade or raw diet, or even a hydrolyzed diet, which breaks down the proteins into smaller pieces that are unrecognizable by the immune system.

How Are Food Allergies Identified in Cats? | Pro Plan Veterinary Diets Once the allergen is identified it should not be fed again. Cats that are treated for food allergies have a good prognosis. The patient will need follow up visits to monitor his progress and to re-examine his skin. If the cat had a bacterial infection, a complete blood count (CBC) will need to be retaken. Occasionally cats can develop new food allergies; the process of an elimination diet will need to be redone.

Thank you for the informative post. I have pet cats and your post has been pretty helpful in understanding the problems of food allergies among pets and the treatment for the same. It is essential to keep a check on your pet’s diet and be careful enough to notice any behavioral changes or other symptoms in them, so that you know what causes the food allergy or food intolerance and change their diet accordingly, take precaution, and treat them.

Food Allergies & Intolerance in Cats - Pet Education


Reported concurrent gastrointestinal (GI) signs among dogs with cutaneous signs of food allergy are rare; it is unknown if this is due to a true dearth of GI signs or if in fact changes in the stool of these dogs were relatively subtle and/or were not noted or volunteered by the owners while obtaining the history. However, a recent report documented 20 dogs with both pruritus and GI signs typical of colitis: fecal mucus, fecal blood, tenesmus and increased fecal frequency. Both cutaneous and GI signs resolved upon feeding the dogs an elimination diet. Lymphocytic-plasmacytic colitis has been linked to food allergy in cats and cheetahs.Certainly, some owners are unable or unwilling to cook for their pet for the period necessary. In such cases, the dermatology service at UC Davis uses commercially available limited-antigen diets. For dogs these would include Purina LA (salmonid); Iams FP (fish and potato) and KO (kangaroo and oats); IVD duck, venison, whitefish, or rabbit plus potato; Hills D/D (duck or fish and rice); or Waltham fish and rice. For cats, these would include IVD duck, venison, or rabbit plus potato; Hills D/D feline; or Iams lamb and barley. Another option for animals who already have been fed many foods, or whose dietary history is unknown, is the use of hydrolyzed protein diets, in which the protein source is hydrolyzed to small molecular weights, thus avoiding the body’s “immunologic radar.” Such foods include Purina HA (hydrolyzed soy), Hills Z/D, or DVM Exclude. Use of a commercially prepared diet will give an approximately 90% chance of determining a food allergy; however, none of these diets will work for all animals, and failure of an animal to improve on such a diet may warrant trying another one, or a home-cooked diet in another trial.
