For a healthy adult cat, a common guideline is about 20–35 calories per pound of body weight per day, which works out to roughly 200–250 calories daily for a 10‑pound cat, but this must be adjusted for age, activity level, and body condition. Always confirm the exact portion using the calorie information on your cat food label and, when in doubt, ask your vet for a tailored plan.

Quick Scoop

1. The basic math: how much food?

Most adult indoor cats need around 200–250 calories per day if they weigh about 8–10 lb and are moderately active.

Many nutrition guides suggest about 25–35 calories per pound of body weight per day for adult cats, with lower amounts for sedentary or overweight cats.

As a rough example:

  • 8 lb cat: about 200 calories/day.
  • 10 lb cat: about 230–250 calories/day.
  • 12 lb cat: about 260–300 calories/day, less if overweight and on a vet‑approved diet.

Always translate calories into grams or cup measures using the feeding chart on your specific food bag or can, because different brands have different calorie densities.

2. Dry vs wet: what that looks like

Exact amounts depend on the brand, but many adult feeding charts land in these ballparks for a typical, average‑calorie cat food:

  • Dry food only: about 1/3–2/3 cup per day for a 5–9 lb cat; 3/4–1 cup for a 10–14 lb cat.
  • Wet food only: many 10‑lb adults do well on roughly one 3–3.5 oz (85–100 g) can per day, sometimes split into two smaller cans if the formula is lower calorie.
  • Mixed feeding (common approach): something like 1/4 cup dry plus 2–3 oz wet per day for an average‑size adult, divided into two meals.

These are starting points only; monitor your cat’s weight and adjust by 5–10% as needed over a few weeks.

3. Age matters (kittens, adults, seniors)

Cats at different life stages need different amounts and meal patterns.

  • Kittens (up to ~6 months)
    • Need 2–3 times the calories of an adult per pound of body weight.
* Often eat 3–4 (or more) small meals per day.
  • Adult cats (1–7 years)
    • Usually fine on 1–2 meals per day totaling ~25–35 calories per pound.
  • Senior cats (7+ years)
    • Often need slightly fewer calories (for less activity) or more (if underweight or ill); many guides recommend 2–3 smaller meals per day.

Pregnant and nursing cats can require two to three times their usual intake and must follow a vet‑approved feeding plan.

4. How often should you feed?

Feeding schedule affects behavior, weight, and digestion.

  • Kittens: 3–4 meals per day to support rapid growth.
  • Adult cats: 1–2 meals per day; some owners split the daily portion into morning and evening.
  • Seniors: 2–3 smaller meals can be easier to digest and help keep weight stable.

Free‑feeding (leaving food out all day) raises the risk of overeating and obesity in many cats, especially with dry food.

5. Signs you’re feeding the right amount

You can fine‑tune portions by watching your cat’s body and behavior.

Look for:

  • Waist visible from above and a slight tummy tuck from the side, not a round football shape.
  • Ribs easy to feel with light pressure but not sharply visible.
  • Stable weight over several weeks when measured on the same scale.
  • Normal energy, normal stool, and no constant desperate begging (some begging is just habit!).

If your cat is gaining weight, cut the daily calories by about 5–10% and reassess over a month, preferably under veterinary guidance.

6. When to call the vet

Contact your vet promptly if:

  • You’re not sure how much to feed a cat with diabetes, kidney disease, hyperthyroidism, or other medical conditions.
  • Your cat is losing or gaining weight quickly, despite similar feeding amounts.
  • Appetite suddenly changes (eating much more or much less) without an obvious reason.
  • You’re feeding a pregnant, nursing, or very young kitten and need exact targets.

7. A quick example day

For an average, healthy, mostly indoor 10‑lb adult cat:

  • Daily target: ~220–240 calories.
  • Option A – dry only: check the bag; if it’s 350 kcal per cup, you’d feed about 2/3 cup per day (240 ÷ 350 ≈ 0.7 cup), split into two meals.
  • Option B – wet only: if one can is ~180 kcal, you might feed 1¼–1½ cans per day, split into breakfast and dinner.
  • Option C – mixed: 1/4 cup dry (≈90 kcal) plus 1 small 3 oz can wet (≈120–150 kcal), adjusted to hit your target.

Monitor every few weeks and tweak up or down to keep your cat in a lean, healthy condition.
