FAQ
How do I calculate daily calorie needs for my pet?
Use the RER formula (Resting Energy Requirement): RER = 70 × weight(kg)^0.75, then multiply by activity level, life stage, and neuter status factors to get Daily Energy Requirement (DER).
How do I convert between dry and wet food?
Dry food is ~300-400 kcal/cup; wet food (canned) is ~80-120 kcal/100g. This calculator estimates dry food portions — use packaging calorie information for wet food conversion.
How can I help my overweight pet lose weight?
Calculate calorie needs based on ideal weight (not current weight), feed at 80%. Weekly weight loss should not exceed 1-2% of body weight. Consult a vet for severe obesity cases.
