How Vets Actually Choose a Cat Food
Most pet owners don’t realize this, but WSAVA does not directly “approve” specific cat food brands. Instead, they provide a set of questions that veterinarians and pet owners should ask before choosing a food.
Here are the WSAVA guide questions every cat owner can use:
1. Does the brand employ a full-time qualified nutritionist with a PhD in animal nutrition or a veterinary nutrition specialist?
2. Who formulates the food, and what are their credentials?
3. Has the food been tested through AAFCO feeding trials (not just nutrient analysis)?
4. Where is the food manufactured? Are quality controls in place?
5. What research has the company conducted? Is any of it published in peer-reviewed journals?
6. Will the company share a complete nutrient analysis upon request?
The 5 brands on this list all answer yes to these questions. Most other brands — especially small, boutique, or “natural” brands — do not.
One important caveat: veterinary nutrition is evolving, and your vet knows your cat better than any list can. Always consult your vet before making a major diet change — especially if your cat has a medical condition.
