Daily Calorie Estimator - Feline

How many calories a day does a cat need? The Feline Daily Calorie Estimator will do all the math to help you determine daily calories needs. Calorie requirements can vary greatly depending on the cat’s size, age, metabolism, activity level, environment, temperature, and humidity. Two cats of the same breed and size living in the same environment can have completely differing energy (calorie) requirements. (See MER and DER below) “Individual pet needs can vary by as much as 50% from calculated values however, so these are only starting points for estimating the amount of food to be provided daily.[6]

A good starting point to establish your cat’s calories needs is to determine the total calories they are currently getting each day in the form of food and treats. Then determine their body condition score (BCS) and muscle condition score (MCS) to evaluate whether your dog needs the same (maintenance), or more or less calories each day. You should work with your veterinarian to determine your cat’s BCS and MCS and his/her ideal weight.

There are three commonly used terms for measurements of daily energy needs. The calculation of the MER or DER is based increasing Resting energy requirement (RER) to account for daily activity, work, growth, gestation, or lactation.
