The Resting Energy Requirement (RER) is the baseline number of calories your pet needs at rest. It's calculated using the formula: RER = 70 × (body weight in kg)^0.75.
The Maintenance Energy Requirement (MER) adjusts RER based on your pet's activity level, life stage, and whether they're neutered or spayed. This gives you the actual daily calorie target for maintaining a healthy weight.
Pets on limited-ingredient diets (LID) or elimination diets may have different calorie needs. Novel protein sources like venison, duck, or rabbit can vary in calorie density compared to standard chicken or beef formulas. Always check the calorie content per cup or can when switching to a hypoallergenic food.
