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 weight | About this many calories a day |
|---|---|
| 8 lb | 220 |
| 10 lb | 260 |
| 12 lb | 300 |
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.

Stay consistent with meals, treats and weight.

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.
