Daily food calculator
Enter your cat's weight and the calorie density on the label to get grams per day — the number most feeding guides skip.
Based on resting energy requirement (RER = 70 × kg^0.75) times a life-stage factor, divided by the food's calorie density. Treat it as a starting point: weigh your cat monthly and adjust by 10% at a time. Wet food contains roughly 80% water, so compare on a dry-matter basis.
