What to Look For in Hypoallergenic Cat Food

When choosing hypoallergenic cat food, consider these important factors:

Limited Ingredients

Hypoallergenic foods should have a minimal ingredient list, typically featuring a single protein source and limited carbohydrates. This makes it easier to identify and avoid specific allergens.

Novel Protein Sources

Novel proteins like duck, rabbit, venison, or kangaroo are less likely to cause allergic reactions since most cats haven't been exposed to them. These proteins help avoid common allergens like chicken or beef.

Hydrolyzed Protein

Some hypoallergenic foods use hydrolyzed proteins, which are broken down into smaller molecules that are less likely to trigger immune responses. These are often recommended by veterinarians for severe allergies.

Grain-Free or Limited Grains

While grain allergies are less common in cats than protein allergies, some hypoallergenic foods are grain-free or use limited, easily digestible grains like rice or oats.
