Frequently Asked Questions

What is RER in pet nutrition?

Resting Energy Requirement (RER) is the energy needed for basic body functions at rest. It is calculated as 70 x (body weight in kg)^0.75.

How does MER differ from RER?

Maintenance Energy Requirement (MER) adjusts the RER based on the pet's activity level, age, and reproductive status to give a more realistic daily target.

Do neutered pets need fewer calories?

Yes. Neutering or spaying typically reduces a pet's metabolic rate, requiring a reduction in daily calories to prevent unwanted weight gain.
