About This Cat Food Calculator
This free cat food calculator estimates how much food your cat needs per day based on their weight, age, activity level and whether they are desexed.
Cats are obligate carnivores with specific nutritional needs that differ from dogs and humans. Getting the right daily food amount is essential — both overfeeding and underfeeding can lead to serious health problems.
Wet Food vs Dry Food for Cats
Wet food has higher moisture content (70-80%) which helps with hydration, urinary tract health and is often more palatable. Dry food is more convenient and helps with dental health. Many vets recommend a combination. Always ensure fresh water is available regardless of food type.
Frequently Asked Questions
How many times a day should I feed my cat?+
Adult cats do well with 2 meals per day. Kittens need 3-4 smaller meals. Free feeding (leaving food out all day) can lead to overeating in some cats.
How do I know if my cat is overweight?+
You should be able to feel your cat's ribs without pressing hard. From above, there should be a slight waist. If you cannot feel ribs or see no waist, your cat may be overweight — consult your vet.
Do indoor cats need fewer calories?+
Generally yes — indoor cats are less active than outdoor cats and typically need 20-30% fewer calories.
Should I feed my cat grain-free food?+
Grain-free is not necessarily better. Cats need high-quality protein, not grain-free diets per se. Choose food that meets AAFCO or Australian standards for your cat's life stage.
When should I switch my kitten to adult cat food?+
Most cats can transition to adult food at 12 months. Large breed cats may benefit from staying on kitten food slightly longer.
