Cat Food Allergies: Elimination Diet Guide

Food Allergies vs. Intolerances

True food allergies involve an immune response to specific proteins (most commonly beef, dairy, fish, or chicken). Food intolerances cause digestive upset without immune involvement.

Signs of Food Allergies

• Chronic itching, especially around the face and neck
• Recurrent ear infections
• Vomiting or diarrhea
• Excessive grooming and hair loss

The Elimination Diet

Phase 1: Novel Protein (8-12 weeks)

Feed a diet with a protein your cat has never eaten (rabbit, venison, or duck) and a single carbohydrate source. NO treats, table scraps, or flavored medications during this period.

Phase 2: Challenge

If symptoms improve, reintroduce the original food. If symptoms return within 2 weeks, food allergy is confirmed.

Phase 3: Identification

Reintroduce individual proteins one at a time (2 weeks each) to identify specific allergens.

Important Notes

Blood and saliva tests for food allergies are NOT reliable in cats. The elimination diet is the only accurate diagnostic method. Work with your vet to ensure nutritional adequacy throughout the trial.
