How many calories does an adult Manx cat need per day?

Most adult neutered Manx cats need approximately 185–310 kcal per day depending on weight (3.6–5.4 kg range) and activity level. Use a calorie calculator as a starting point and adjust based on body condition score over time.

Do Manx cats need more calories because of their muscular build?

Muscle tissue is metabolically active, so a very muscular cat does have a slightly higher RER than a fat cat of the same weight. However, a typical indoor Manx adult does not need significantly more calories than similarly-sized cats — portion control and body condition monitoring remain important.

How do I convert my Manx's calorie target into a food portion?

Divide the daily calorie target by the kcal per cup (for dry food) or kcal per can (for wet food) listed on the packaging. For example, if your Manx needs 220 kcal/day and your dry food has 380 kcal/cup, feed approximately 0.58 cups (about 58 g) per day.
