Estimate for healthy adult pets. Puppies, kittens, pregnant or sick animals have different needs: ask your veterinarian.

How the calculator works

• Resting energy requirement is calculated with the standard veterinary formula: 70 multiplied by the body weight in kilograms raised to the power of 0.75.
• Estimated daily calories are the resting requirement multiplied by a factor for the pet’s profile, for example 1.6 for a neutered adult dog or 1.2 for a neutered adult cat.
• Food per day is the daily calories divided by the calories per cup printed on your pet food bag.
• Portion per meal is the daily amount divided by the number of meals, which is the figure to program into an automatic feeder.

Before you change your pet’s diet

These figures are a starting point. Individual needs vary with age, activity and health, and treats count toward the daily total. Weigh your pet regularly, adjust gradually, and ask your veterinarian before starting a weight-loss plan.
