How much should I feed my cat?

Most cats do best on a measured amount each day. Here's how to find a starting point and adjust from there.

Feeding guides on the bag are a starting point, but they often run high. A more reliable way is to start from your cat's calorie needs, then measure every meal.

Step 1: Estimate daily calories

Vets often start with the resting energy requirement (RER) and multiply by a factor for your cat's life stage. For a typical spayed or neutered adult indoor cat, that works out to roughly:

Cat's weightAbout this many calories a day
8 lb220
10 lb260
12 lb300

Kittens need about twice as much per pound, and less active or overweight cats often need less. Our free pet food calculator has a cat option that works this out for your cat's weight and life stage.

Step 2: Turn calories into food

Check the label for calories: dry food lists "kcal per cup," and wet food lists "kcal per can." Then divide:

  • Dry: daily calories ÷ kcal per cup = cups per day
  • Wet: daily calories ÷ kcal per can = cans per day
  • Mixing both: split the calories between them, for example half from wet and half from dry

Measure with a real measuring cup or a kitchen scale. "A scoop" is often much more than a cup.

Step 3: Watch the weight and adjust

Weigh your cat every few weeks. You should be able to feel the ribs easily without pressing hard, and see a waist from above. If your cat is gaining, cut food by about 10% and check again in a few weeks.

Don't forget treats

Treats should stay under about 10% of daily calories. Count them in the total.

Questions people ask

How many times a day should I feed my cat?

Most adult cats do well with two or more measured meals a day. Some cats like several small meals. Kittens usually eat three or four times a day.

Is free-feeding OK for cats?

Leaving food out all day makes it easy for many cats to overeat. Measured meals make it easier to keep a healthy weight.

How do I know if my cat is overweight?

If you can't easily feel the ribs, or can't see a waist from above, your cat may be carrying extra weight. Your vet can confirm and suggest a target.
