Cat Calorie Calculator
Estimate your cat daily calorie needs with the resting energy and maintenance energy method used in feline nutrition. The tool computes resting energy requirement as seventy times body weight in kilograms raised to the power of 0.75, then multiplies by a factor chosen for your cat, since a neutered indoor cat needs far fewer calories than an active intact cat, a growing kitten, or a cat on a supervised weight loss plan. Enter the weight in kilograms or pounds and select the closest life stage to see both the resting figure and the adjusted maintenance figure in calories per day. Cats are prone to obesity, so portioning to a sensible target and monitoring body condition matters. This runs entirely in your browser and is general information only, not veterinary advice, so confirm targets and any weight loss plan with your vet.

Frequently asked questions
How are cat daily calories worked out?
It first finds resting energy requirement as 70 times body weight in kg to the power 0.75, then multiplies by a life stage factor to get maintenance energy requirement for a full day.
What factor does a neutered indoor cat use?
A neutered indoor adult cat typically uses a factor near 1.0 to 1.2, while active, intact, or pregnant cats use higher multipliers. Kittens use the highest factors for growth.
Why do cats need fewer calories than expected?
Most indoor cats are far less active than their size suggests, so their maintenance factor is low. Overfeeding is common, which is why the calculator separates resting and maintenance figures.
