Pet Food Calculator

Use RER formula: 70 × weight in kg^0.75, then multiply by activity factor. A 50 lb moderately active dog needs about 1,100-1,300 calories per day, or roughly 3 cups of dry food.

Indoor cats need 20-25 calories per pound of body weight. A 10 lb indoor cat needs about 200-250 calories/day, roughly 1/3 to 1/2 cup of dry food.

Puppies (under 6 months): 3 meals/day. Adult dogs: 2 meals/day. Kittens: 3-4 meals/day. Adult cats: 2 meals/day.
