Formula
Every pet is different. This is the standard vet formula (RER = 70 × weight_kg^0.75, MER = RER × life-stage/activity factor). Actual needs vary by breed, metabolism, medical conditions, and food quality. If your pet gains or loses weight on this amount, adjust by 10% and re-check in 2 weeks.
