Buying Guide
A protein is only ‘novel’ if your cat has never eaten it before. Track all proteins your cat has consumed throughout its life. The most reliably novel proteins for most cats are kangaroo, alligator, venison, and rabbit, as these are rarely included in mainstream formulas.
Key Nutritional Criteria to Evaluate
When choosing the best food for your cat’s specific needs, always look for:
- AAFCO Statement: Ensure the food is “complete and balanced” for your cat’s life stage
- Named protein source: Real chicken, salmon, etc. — not generic “meat” or “poultry”
- Moisture content: Higher moisture (wet food) benefits hydration
- Ingredient quality: Avoid artificial colors, flavors, and preservatives
Frequently Asked Questions
What counts as a novel protein for cats?
A novel protein is any animal protein your specific cat has never eaten before. Common options include rabbit, venison, duck, kangaroo, bison, and alligator.
How long until a protein is no longer novel?
Once a cat is exposed to a protein repeatedly, the immune system can mount a response. A protein that was once novel can become an allergen with repeated exposure, which is why rotation diets are sometimes recommended.
Can I use novel proteins without a vet diagnosis?
Yes. Novel protein diets are available over the counter. However, a veterinary consultation is recommended to properly diagnose food allergies and develop an elimination diet protocol.
What are the most exotic novel proteins available in cat food?
Kangaroo, alligator, ostrich, bison, wild boar, and guinea fowl are among the most exotic novel proteins available. These are offered by specialty brands.
