Buying Guide

Confirm veterinary prescription requirements

Many therapeutic diets are prescription-only—verify with your veterinarian that a veterinary diet like Hill's c/d or i/d is appropriate before purchasing

Match the diet to the clinical condition

Choose a formula targeted to the specific issue—urinary-care formulas for lower urinary tract disease, i/d for digestive sensitivity, and m/d for glucose or weight management

Check guaranteed analysis and primary ingredients

Compare protein, fat, fiber, and moisture levels as well as key ingredients to ensure the formula supports your cat's medical needs and tolerances

Consider dry vs. therapeutic wet options

Dry diets can be more economical and convenient, while wet therapeutics may increase water intake for urinary or renal concerns—choose based on medical advice and hydration needs

Monitor response and follow-up with vets

Track clinical signs, weight, and lab results after switching to a veterinary diet and consult your veterinarian to adjust therapy if goals aren't met
