Most healthy adult cats need somewhere between 24 and 35 calories per pound of body weight per day, which usually works out to roughly 4 to 6 ounces of wet food or 1/4 to 1/2 cup of dry food daily, split into two meals. That range is a starting point, not a rule, because the right amount depends on your cat’s weight, age, activity level, and whether they’ve been spayed or neutered. Below you’ll find feeding charts, calorie math, and the practical signals that tell you whether you’ve got it right.
Quick Answer
If you want a fast estimate before reading the details:
- A lean 8-pound indoor cat needs about 180–220 calories per day.
- A 10-pound cat typically needs 220–280 calories per day.
- A 12-pound cat often needs 260–320 calories per day.
Translate those calories into your specific food using the label, because brands vary widely. A 3-ounce can of pâté might hold 90 calories, while another holds 70. Dry food ranges from 300 to over 500 calories per cup. The calorie number printed on the package matters far more than the scoop you happen to use.

Feeding Chart: Practical Examples
This chart assumes a healthy, neutered adult cat at a normal body condition. Use it as a launch point and adjust based on your cat’s response.
| Cat’s Weight | Daily Calories | Wet Food (~90 cal/3 oz can) | Dry Food (~400 cal/cup) |
|---|---|---|---|
| 6 lb | 150–180 | ~2 cans | ~3/8 cup |
| 8 lb | 180–220 | ~2.5 cans | ~1/2 cup |
| 10 lb | 220–280 | ~3 cans | ~5/8 cup |
| 12 lb | 260–320 | ~3.5 cans | ~3/4 cup |
| 15 lb | 300–360 | ~4 cans | ~7/8 cup |
Keep in mind that a 15-pound cat may be overweight, so the goal might be to feed for the cat’s ideal weight rather than current weight. When in doubt, ask your vet to assign a body condition score.
Calories Matter More Than Cups
The single biggest mistake cat owners make is measuring food by volume without checking calories. “Half a cup” means nothing on its own, because two bags sitting on the same shelf can differ by 150 calories per cup. That gap is enough to push a cat from a healthy weight toward obesity over a few months.
Flip the bag or can over and find the kcal/cup or kcal/can line, usually printed near the guaranteed analysis. Divide your cat’s target daily calories by that number, and you’ll know exactly how much to serve. A kitchen gram scale beats a measuring cup for accuracy, especially with dry food, where a loosely filled scoop can hide a 20% error.
This habit also makes treats and table scraps easier to manage. Treats should stay under 10% of daily calories, and that includes the bits of chicken, salmon, or egg you share from your plate.
Wet Food Guidance
Wet food runs around 70–100 calories per 3-ounce can and 150–250 calories per 5.5-ounce can, though pâté tends to pack more calories than chunks in gravy. Because wet food is roughly 75% water, it supports hydration, which is helpful for cats prone to urinary issues or those who simply don’t drink much.
A typical adult cat eating only wet food needs about two to four 3-ounce cans per day, depending on weight. Serve it at room temperature for better acceptance, and toss anything left out longer than a couple of hours to avoid spoilage.
For a deeper breakdown by weight and can size, see our guide on how much wet food to feed a cat. If you’re weighing the pros and cons of textures, the comparison in wet vs dry cat food lays out the tradeoffs clearly.
Dry Food Guidance
Dry food (kibble) is calorie-dense, often 300–500+ calories per cup, which is why small measuring errors add up fast. A cat eating dry food alone usually needs only 1/4 to 1/2 cup per day — a portion that surprises many owners who’ve been filling the bowl by eye.
Kibble stays fresh in the bowl, which makes it convenient for scheduled or portion-controlled feeding, but that convenience also makes overfeeding easy. Measure each meal, and store the bag sealed to preserve flavor and nutrients.
Our dedicated article on how much dry food to feed a cat walks through the math for common weights. If your cat suddenly turns up their nose at kibble, the reasons explored in why your cat is not eating dry food may help.
Mixed Feeding Guidance
Plenty of owners feed both wet and dry, and that’s a perfectly reasonable approach. The trick is counting the calories from both sources together rather than treating each as a full meal.
A practical split for a 10-pound cat needing 250 calories might look like one 3-ounce can of wet food (about 90 calories) in the morning and the rest made up with measured dry food across the day. Mixed feeding gives you the hydration benefits of canned food and the convenience of kibble, while letting you control total intake.
Just resist the urge to “round up” both portions. If you find yourself adding a little extra to each, you’ve quietly doubled the surplus.
Factors That Change Feeding Amounts
No single chart fits every cat, because calorie needs shift with several variables:
- Body condition. An overweight cat should be fed for its target weight, often with a vet-guided weight-loss plan, while an underweight cat may need more.
- Age. Kittens burn enormous energy and need frequent, calorie-rich meals — see our kitten feeding chart by age. Senior cats often need adjustments too, covered in the senior cat feeding guide.
- Neuter status. Spaying and neutering lower a cat’s metabolic rate, so fixed cats typically need fewer calories than intact ones.
- Activity level. A busy indoor-outdoor hunter burns more than a sofa-loving indoor cat. The differences are explored in indoor cat food vs regular cat food.
- Pregnancy and nursing. Queens may need two to three times their normal calories, and this should always be managed with veterinary input.
- Medical conditions. Diabetes, kidney disease, hyperthyroidism, and other conditions all change feeding needs and sometimes require prescription diets.
How often you serve those calories matters as well. Some cats do better grazing, others on a clock — the discussion in free feeding vs scheduled feeding and how often you should feed a cat can help you decide.
Signs You May Be Feeding Too Much
Your cat’s body tells you more than any chart. Watch for these signals:
- You can no longer easily feel the ribs under a light fat layer.
- The waist disappears when viewed from above; the body looks more oval than hourglass.
- A pronounced belly pouch that sways noticeably when walking.
- Steady weight gain at weekly or monthly weigh-ins.
- Reduced grooming on the lower back and tail base, often a sign the cat can’t reach.
Excess weight raises the risk of diabetes, joint problems, and a shorter lifespan, so trimming portions early pays off.
Signs You May Be Feeding Too Little
Underfeeding is less common but just as concerning:
- Ribs, spine, and hip bones feel sharp or are visible.
- A sunken belly and obvious loss of muscle along the back.
- Low energy, dull coat, or increased food-seeking and vocalizing.
- Gradual weight loss over weeks.
Persistent hunger doesn’t always mean underfeeding, though. If your cat acts ravenous despite adequate meals, the causes in why your cat is always hungry are worth a read, since some are medical.
When to Ask a Vet
Portion math is a helpful tool, but it doesn’t replace professional judgment. Talk to your veterinarian before making major diet changes or if your cat is underweight, overweight, sick, pregnant, nursing, or very young. Sudden appetite changes, unexplained weight shifts, vomiting, or lethargy all warrant a call.
A vet can assign an accurate body condition score, rule out underlying disease, and tailor a feeding plan to your cat’s specific needs. When you do switch foods, do it gradually — the steps in how to transition cat food safely reduce the risk of stomach upset.
FAQ
How many times a day should I feed my cat?
Two meals a day suits most adult cats, though some thrive on three smaller portions or free-fed kibble in controlled amounts. Kittens need more frequent feeding. The key is keeping the total daily calories consistent regardless of how you split them.
Should I feed my cat wet or dry food?
Both can be complete and balanced. Wet food adds hydration, while dry food offers convenience and dental texture. Many owners combine the two. See is wet food better for cats for the evidence behind each.
How do I know if my cat’s food is high quality?
Look for an AAFCO statement confirming it’s complete and balanced for your cat’s life stage, a named animal protein as the first ingredient, and a brand that conducts feeding trials. Guides on high protein cat food and grain-free cat food cover specific categories.
Can I free-feed my cat?
Free-feeding works for some cats but encourages overeating in others, especially food-motivated indoor cats. Portion-controlled meals make it easier to track intake and spot appetite changes early.
How much should I feed an overweight cat?
Feed for the target weight, not the current weight, and reduce calories gradually under veterinary supervision. Crash diets are dangerous for cats and can cause a serious liver condition called hepatic lipidosis.
Do treats count toward daily calories?
Yes. Treats and human-food extras should make up no more than 10% of daily calories. That includes shared foods — check our guides on whether cats can eat tuna, cheese, or shrimp before offering them.
Why does the bag’s recommendation seem like too much?
Bag guidelines are often generous and may not account for your cat’s neuter status or activity level. Use them as a ceiling, then adjust downward based on body condition.
How long until I see results after changing portions?
Aim for slow change. A healthy weight-loss rate is about 0.5–2% of body weight per week. Reassess monthly and adjust as needed.
Conclusion
Feeding your cat the right amount comes down to three habits: estimate daily calories based on your cat’s ideal weight, read the label so you know what’s actually in the bowl, and watch your cat’s body for the feedback that no chart can provide. Most adult cats land in the 180–280 calorie range, but the healthiest number is the one that keeps your specific cat lean, energetic, and at a steady weight.
When something feels off — too thin, too round, or simply different from usual — your veterinarian is the best partner for fine-tuning the plan. Get the foundation right, adjust as your cat ages, and the daily question of “how much” becomes a lot less stressful.
