How many calories does your pet need?

Knowing what to feed is easy. Knowing how much is the hard part.

Every pet is different, and factors like age, size, and breed make a big difference.

To account for this, we calculate your pet's Maintenance Energy Requirement (MER). It represents the total estimated number of calories your pet needs each day, factoring in body weight, age, activity level, and life stage.

Calculate your pet's MER

Our MER calculator can put you and your pet on the right track, generating an estimated daily calorie target based on your unique pet. *For adult pets only
