MER Calculator for Cats

If a goal of “maintain weight” is selected for a pet with a BCS of 6 or 7, slow weight loss could occur since MER will be based on a lower body weight. However, selecting “lose weight” as the goal will provide greater calorie restriction, which may facilitate faster weight loss. Calories should be gradually decreased for safe, effective weight loss. If a pet is underweight, selecting “maintain/gain weight” should encourage slow weight gain since MER will be based on a higher body weight. However, desired weight gain may not occur until contributing conditions are identified and managed, especially in pets with a BCS of 1 or 2.
