Cat Food Calculator
Estimate your cat's daily calories and food from its weight and lifestyle.
Cats are small, so the numbers are small — a lazy indoor cat often needs only 180 to 250 kcal a day. Kittens burn far more per pound because they're still growing.
How it works
A cat's calorie needs come down to weight and lifestyle. An indoor cat lounging by the window needs noticeably less than an active outdoor cat or a growing kitten building its body.
The tool estimates resting energy from your cat's weight, then applies a factor for its situation — indoor, active, or kitten — to reach a daily calorie target you can feed to.
Kittens and pregnant or nursing cats need considerably more per pound than a settled adult, which is why picking the right category matters as much as the weight.
Frequently asked questions
How many calories does a cat need per day?
A typical indoor adult cat needs roughly 20 calories per pound of body weight, more if very active and much more as a growing kitten. Enter your cat's details for a tailored figure.
Should I feed a kitten more than an adult?
Yes, quite a bit more per pound. Kittens are building bone and muscle fast, so they need extra energy relative to their small size.
Is my indoor cat overfed?
Many are. Indoor cats burn less and weight creeps up easily, so measuring portions against a calorie target rather than filling the bowl helps keep them trim.
