Cat Food Portion Calculator

Cat Nutrition Basics

Cats vs Dogs

Cats are obligate carnivores with different nutritional needs to dogs. They require taurine (found only in animal tissue), cannot synthesise niacin or certain fatty acids, and have a naturally low thirst drive — making high-moisture wet food especially beneficial.

Wet vs Dry Food

Wet food provides hydration alongside nutrition — particularly important for cats prone to urinary issues or kidney disease. Dry food is more calorie-dense and practical. Many vets recommend a primarily wet food diet with dry food for dental benefits.

Indoor vs Outdoor

Indoor cats typically need 200–250 kcal/day. Active outdoor cats need 300–400 kcal/day. Neutered cats have 20–30% lower energy needs than intact cats of the same weight. Adjust based on body condition.
