Frequently Asked Questions (FAQ)

Q: Can I mix Core and Complete Health foods?A: Yes, you can. Both lines share a similar philosophy of natural ingredients, making them compatible for mixing to provide variety or transition between lines.
Q: Is Wellness good for cats with kidney disease?A: Neither Wellness Core nor Complete Health is formulated as a prescription renal diet. Cats with kidney disease require specific nutrient profiles; always consult your veterinarian for dietary recommendations.
