Frequently asked questions
- What is RER?
- Resting Energy Requirement (RER) = 70 × weight(kg)^0.75. It is the energy needed by a healthy pet at rest in a thermoneutral environment.
- What is MER?
- Maintenance Energy Requirement (MER) = RER × a life-stage factor. It accounts for normal daily activity and physiological status.
