Question 1

How much should I feed my cat per day?

Accepted Answer

A typical 4.5kg adult cat needs around 250-280 kcal per day, which is roughly 65-75g of dry food or 230-260g of wet food. Indoor cats need about 10% fewer calories than outdoor cats. PFMA guidelines recommend adjusting portions based on body condition rather than relying solely on weight.

Question 2

Is wet or dry cat food better?

Accepted Answer

Both can provide complete nutrition. Wet food has higher moisture content (around 80%), which helps with hydration -- important for cats who do not drink enough water. Dry food is more energy-dense, so you need far less by weight. Many UK vets recommend a combination of both for optimal nutrition and dental health.

Question 3

Do neutered cats need less food?

Accepted Answer

Yes. Neutered cats have lower energy requirements than intact cats. The PDSA estimates neutered cats need around 20% fewer calories to maintain a healthy weight. This calculator uses a neutered-adult multiplier that accounts for this reduced metabolic rate.
