Cat Food Portion Calculator
Cats are notoriously good at convincing owners they're underfed. Use this calculator to find the correct portion for your cat's actual needs.
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.
Preventive Veterinary Care
Regular preventive veterinary care reduces long-term costs and improves pet health outcomes. Annual vaccinations (dogs and cats) protect against serious diseases. Regular flea, tick, and worm treatments prevent infestations and parasite-borne diseases. Annual dental checks — dental disease affects over 80% of dogs and cats over 3 years old and causes chronic pain that is often undetected. Microchipping is compulsory for dogs in England and recommended for cats. Pet insurance taken out when pets
