Buying Guide

Match diet to the diagnosed condition

Choose a formula specifically formulated for the condition diagnosed by your veterinarian—urinary, renal, digestive, thyroid, weight, hypoallergenic or diabetes support

Confirm veterinary authorization requirements

Some veterinary prescription diets require a veterinary recommendation or prescription—check with your clinic before purchasing

Compare protein and sodium levels

For kidney and thyroid support, look for controlled protein and reduced sodium; for digestive issues, seek highly digestible ingredient sources

Watch for hydrolyzed or novel proteins

If food allergy or intolerance is suspected, hydrolyzed-protein or hypoallergenic formulas can reduce immune reactions

Consider calorie density for weight or diabetes

Weight-reduction and glucose-management diets differ in calorie density and carbohydrate composition—choose the one aligned with your cat's energy needs

Evaluate packaging size and feeding cost

Match bag or can size to your cat's appetite and shelf life to reduce waste and maintain freshness between servings
