How Much to Feed a Cat: Daily Portion Guide
Start here
Most adult indoor cats need roughly 180 to 250 calories a day, which usually works out to a few small meals of wet and/or dry food — but the right amount depends on your cat's ideal weight, age, activity, and whether they're spayed or neutered. The most reliable approach is to feed to your cat's ideal body condition, use the feeding guide on the label as a starting point, and adjust based on the scale and how your cat looks and feels.
Start with calories, not cups
Cats are small, and their needs vary a lot, so a generic "one cup a day" rarely fits. A better anchor is daily calories. As a rough guide, many spayed or neutered indoor adult cats maintain weight on somewhere around 180–250 kcal per day, with lean, active, or younger cats needing more and sedentary or overweight cats needing less.
Every complete cat food lists calories as kcal per cup or per can (look for the "calorie content" statement). Once you know your food's kcal and your cat's daily target, the math is simple: daily target ÷ food's kcal per unit = how much to feed. Your vet can calculate a precise target for your individual cat, especially if weight loss or gain is the goal.
General starting portions by weight
Use this as a rough starting point for a typical adult cat, then adjust to keep body condition ideal. These are total daily amounts to split across meals:
| Cat's ideal weight | Approx. daily calories | Roughly equals |
|---|---|---|
| 8 lb | ~180–210 kcal | About 1 can (5.5 oz) wet, or a scant ½ cup dry |
| 10 lb | ~210–250 kcal | About 1–1¼ cans wet, or ½ cup dry |
| 12 lb | ~240–280 kcal | Slightly more; recheck body condition |
| 15 lb (if ideal) | ~270–320 kcal | Larger-framed cats only; most 15-lb cats are overweight |
Practical take: Feed for the weight your cat should be, not the weight they are. If a 15-lb cat should be 11, feed for 11 and let the weight come down gradually under your vet's guidance.
Life stage changes the math
How much and what you feed shifts across your cat's life:
- Kittens grow fast and need far more calories per pound than adults, plus a diet labeled for growth. Feed several small meals a day and follow the growth chart on kitten food.
- Adults (roughly 1–7 years): feed a maintenance diet to hold a lean, steady weight. Neutering lowers calorie needs, so portions often drop after surgery.
- Seniors (about 7+): needs vary — some lose weight and need more calories and palatable food, while others slow down and gain. Regular weigh-ins matter most here. See our senior cat diet guidance if kidney changes are in the picture.
Wet, dry, or both — and how many meals
All three approaches can keep a cat healthy if the food is complete and balanced and portions are controlled. What matters is total daily calories.
- Wet food adds water, which supports urinary and kidney health, and is more filling per calorie.
- Dry food is convenient and works well for puzzle feeders, but it's calorie-dense and easy to overfeed by free-choice.
- Mixing both is common and fine — just count the calories from each toward the daily total.
Cats do well with two or more small meals a day. Free-feeding a bowl of kibble all day is a frequent cause of creeping weight gain; measured meals or a food puzzle give you control and mental enrichment.
Check body condition, then fine-tune
The scale plus a hands-on body condition check tells you whether your portions are right. In a cat at a healthy weight, you should be able to feel the ribs easily with light pressure (but not see them), see a visible waist from above, and note a slight tummy tuck from the side. A rounded belly, no waist, and ribs you can't feel point to overfeeding.
Adjust in small steps — a change of about 10% up or down — and recheck in a few weeks rather than making big swings. Any deliberate weight loss should be slow and vet-supervised, because cats who drop weight too fast risk a dangerous liver condition called hepatic lipidosis.
Why weighing beats guessing
Cats are masters at hiding weight change under their coats, and a pound on a 10-lb cat is like roughly 15 pounds on a person — it matters. Weighing every few weeks and logging portions turns feeding from guesswork into a feedback loop: you can see whether the amount you're serving is holding your cat steady, and catch a slow gain or loss long before it becomes a health problem.
Dial in portions with real data
Tavi tracks your cat's weight and body condition over time and keeps your feeding notes in one place, so you can see whether today's portions are keeping your cat lean — and adjust before a slow gain becomes obesity. Free for your first pet.
Frequently asked questions
How much should I feed my cat per day?
Most spayed or neutered adult indoor cats need roughly 180 to 250 calories a day, but the exact amount depends on ideal weight, age, and activity. Use the calorie statement on your food's label to convert that into cups or cans, and adjust based on your cat's body condition. Your vet can give a precise target for your individual cat.
Is it better to feed cats wet or dry food?
Both can keep a cat healthy when the food is complete and balanced and portions are controlled. Wet food adds beneficial water and is more filling per calorie, while dry is convenient but easy to overfeed. Many owners feed a mix; just count all the calories toward the daily total.
How many times a day should I feed my cat?
Two or more small measured meals a day suits most cats and gives you control over portions. Kittens need more frequent meals. Leaving a bowl of kibble out all day often leads to gradual weight gain, so measured meals or a food puzzle are usually better.
How do I know if I'm feeding my cat too much?
Check body condition: in a healthy-weight cat you can easily feel the ribs, see a waist from above, and note a slight tummy tuck. If the ribs are hard to feel, there's no waist, and the belly is rounded, cut portions by about 10% and recheck the weight in a few weeks with your vet's guidance.
Should I feed my cat differently after spaying or neutering?
Yes. Neutering lowers a cat's calorie needs, so many cats gain weight after surgery if portions stay the same. Reducing the amount slightly and monitoring body condition afterward helps prevent post-neuter weight gain.
