Puppy & Kitten Feeding Calculator

How much to feed, how often, and how to know you have got it right. Built by a vet, not a food company. By Dr Duncan Houston.

Your pet

Who are we feeding, and how big are they now?

Pick the species, then enter today’s weight and age. The daily amount and the meal count are worked out from these.

Who are we feeding?
Expected adult size

How big will they get?

Expected adult weight is what makes the amount change as they grow. Search the breed, pick a size, or type the weight if you know it.

Most owners know the breed but not the adult weight. Pick it and we do the maths. Not purebred? Choose “Mixed breed or not sure”.

Their food

What are you feeding them?

Enter the calories printed on the bag. Leave it blank to use a typical estimate.

Look on the bag for “kcal/cup” or “kcal/kg”. Leave blank to use a typical estimate.

Your result

Here is their feeding plan

This calculator is a starting estimate for healthy, growing puppies and kittens. Breed and sex values are approximate adult references, not guaranteed growth targets. Every pet is an individual, so use body condition to fine-tune and check with your vet if your pet is not thriving.

How this tool works

What this calculator works out

Calculate daily feeding needs for puppies and kittens, including calories, food portions, meal frequency, breed size, sex and growth stage.

Ask A Vet also makes a GPS Tracker for dogs and cats. See the GPS Tracker
