You stand at the cupboard, scoop in hand, and that little voice pipes up: am I giving my cat too much, or not enough? If you’ve ever second-guessed that scoop, you’re in good company. Figuring out how much to feed your cat is one of the most common questions cat parents ask, and honestly, the bag’s “feeding guidelines” don’t make it easy.
Here’s the good news. Once you know your cat’s ideal weight and a little simple calorie math, the answer gets clear fast. Let’s sort it out together.
- A healthy indoor adult cat needs roughly 20 calories per pound of ideal body weight per day, so a 10-pound cat needs about 200 calories daily.
- Feed for your cat’s ideal weight, not their current weight, since 61% of US cats are overweight or obese according to the Association for Pet Obesity Prevention.
- Kittens need about two to three times an adult cat’s calories per pound to fuel growth, while senior and overweight cats usually need fewer calories.
- Dry food holds about 300 to 500 calories per cup, while wet food holds roughly 70 to 100 calories per 3-ounce can, so portion sizes look very different by food type.
- Cornell Feline Health Center recommends feeding adult cats once or twice a day, and kittens under six months three times a day.
This article is the hub of our cat feeding guide. We’ll cover how many calories your cat needs, a feeding chart by weight and life stage, how to turn calories into real portions of wet and dry food, how often to feed, and how to tell if you’ve got the amount right. A quick, friendly note first: this is educational, and your veterinarian knows your individual cat best, especially if your cat has a health condition.
How Much Should I Feed My Cat Per Day?
A healthy indoor adult cat needs about 20 calories per pound of ideal body weight per day. Active or outdoor cats can need closer to 30 to 35 calories per pound. So a 10-pound indoor cat usually needs around 200 calories a day, while a busy 10-pound outdoor hunter might need 300 or more.
That calorie number is the real answer to “how much should I feed my cat.” Cups and cans are just the delivery method, and they change depending on the food. Two cats at the same weight can need very different scoop sizes if one eats calorie-dense kibble and the other eats watery pâté.
A few things nudge that calorie target up or down:
- Spay or neuter status: Spayed and neutered cats burn fewer calories, so they need less food than intact cats.
- Activity level: A laser-chasing athlete burns more than a windowsill napper.
- Age: Growing kittens need far more per pound, while many seniors need less.
- Body condition: A cat carrying extra weight needs to eat for the leaner cat you’re aiming for.
- Health: Conditions like hyperthyroidism, diabetes, or kidney disease change the math, so loop in your vet.
Cat Feeding Chart by Weight (Calories Per Day)
This cat feeding chart shows roughly how many calories a healthy adult cat needs per day based on ideal body weight. Use your cat’s ideal weight, not their current weight, if they’re carrying a few extra pounds. These are starting points, and your vet can fine-tune them.
| Ideal Body Weight | Indoor / Less Active (about 20 kcal/lb) | Active / Outdoor (about 30 kcal/lb) |
|---|---|---|
| 5 lb (2.3 kg) | ~100 calories/day | ~150 calories/day |
| 8 lb (3.6 kg) | ~160 calories/day | ~240 calories/day |
| 10 lb (4.5 kg) | ~200 calories/day | ~300 calories/day |
| 12 lb (5.4 kg) | ~240 calories/day | ~360 calories/day |
| 15 lb (6.8 kg) | ~280 calories/day | ~420 calories/day |
| 18 lb (8.2 kg) | ~320 calories/day | ~480 calories/day |
Notice the chart tops out gently at higher weights. That’s on purpose. A heavier cat shouldn’t simply eat more and more, because the goal is usually to bring an overweight cat back toward a healthy size, not to feed the extra weight.
How to Calculate Your Cat’s Calories the Vet Way
Vets use a two-step formula to estimate daily calories, and you can run it on your phone in a minute. First you find the Resting Energy Requirement (RER), the calories a cat burns just existing. Then you multiply by a life-stage factor to get the Maintenance Energy Requirement (MER), the real daily target.
- Find your cat’s weight in kilograms. Divide pounds by 2.2. A 10-pound cat is about 4.5 kg.
- Calculate RER. The formula is RER = 70 × (weight in kg) raised to the power of 0.75. For a 4.5 kg cat, that’s about 208 calories. (No exponent button? A rough shortcut for average cats is 30 × kg + 70, which gives about 205.)
- Multiply by the life-stage factor from the table below to get daily calories (MER).
| Life Stage / Status | Multiply RER By |
|---|---|
| Neutered or spayed adult | 1.2 |
| Intact adult | 1.4 |
| Weight loss needed | 0.8 to 1.0 |
| Active / weight gain needed | 1.2 to 1.4 |
| Kitten, under 4 months | 2.5 |
| Kitten, 4 to 12 months | 2.0 |
| Pregnant cat | 2.0 |
| Nursing cat | 2.0 to 2.5+ |
So a neutered 10-pound indoor cat works out to about 208 × 1.2, or roughly 250 calories, which lands near our 20-to-25-calorie-per-pound rule of thumb. One honest caveat from veterinary nutritionists: individual cats can vary from these estimates by up to 50%. Treat the number as a smart starting point, then adjust based on your cat’s body condition.
How Much Wet vs Dry Food Should I Feed My Cat?
The amount of wet vs dry food to feed your cat depends entirely on how many calories each one packs. Dry food is calorie-dense, so portions look small. Wet food is mostly water, so portions look bigger for the same calories. Once you know the calories per cup or per can, the rest is simple division.
Here’s the part most bags bury: the calorie count is printed on the package as “kcal/kg” and usually “kcal/cup” or “kcal/can.” Find that number, then divide your cat’s daily calorie target by it. That tells you exactly how much to serve.
| Food Type | Typical Calorie Density | Daily Amount for a 10-lb Cat (~200 cal) |
|---|---|---|
| Dry food (kibble) | ~300 to 500 calories per cup | About 1/3 to 1/2 cup |
| Wet food, 3-oz can | ~70 to 100 calories per can | About 2 to 3 cans |
| Wet food, 5.5-oz can | ~150 to 200 calories per can | About 1 to 1.5 cans |
Want to feed both, like a lot of cat parents do? Great, just don’t double up. Pick a split, such as half the calories from wet and half from dry, then measure each to hit the total. For a 200-calorie cat, that might look like one 3-oz can of wet plus a scant 1/4 cup of dry. The single biggest mixing mistake is serving a full bowl of kibble and a full can of wet, which can blow right past the calorie target.
Wet and dry each have perks. Wet food adds moisture, which supports urinary and kidney health and helps cats feel full on fewer calories. Dry food is convenient, budget-friendly, and works well in puzzle feeders. Many vets are happy with either, or a combo.
How Much to Feed a Kitten, Adult, and Senior Cat
How much to feed your cat changes a lot across life stages. Kittens need the most calories per pound to fuel rapid growth, adults need a steady maintenance amount, and many seniors need fewer calories as they slow down. Matching the food to the life stage keeps your cat lean and healthy.
| Life Stage | Calorie Needs | What to Feed | Meals Per Day |
|---|---|---|---|
| Kitten (under 1 year) | About 2 to 3 times the adult amount per pound | Food labeled for kittens or “all life stages” | 3 to 4 small meals |
| Adult (1 to 7 years) | About 20 to 30 calories per pound, by activity | Adult maintenance food | 1 to 2 meals (more small meals is fine) |
| Senior (7+ years) | Often slightly less; adjust to body condition | Senior or adult food, vet-guided | 2 to 3 smaller meals |
Kittens
Kittens are tiny engines, so they need roughly two to three times the calories per pound that an adult cat needs. Feed a food made for kittens, since it’s higher in protein, fat, and calories. Offer small meals often, because little stomachs fill up fast. Free-choice or several scheduled meals a day both work while they’re growing.
Adult cats
Adult cats need a steady maintenance amount, usually around 20 calories per pound of ideal weight for indoor cats and up to 30 or more for active ones. This is the life stage where overfeeding sneaks in, so measure portions instead of topping up the bowl. A standard kitchen measuring cup beats eyeballing it every time.
Senior cats
Senior cats (around 7 years and up) often need slightly fewer calories as their activity dips, though some older cats actually lose weight and need more support. Because aging cats are prone to kidney disease, dental issues, and muscle loss, senior feeding is very individual. Weigh your cat regularly and ask your vet to check body condition at each visit.
How Often Should I Feed My Cat?
Most adult cats do well with one or two meals a day, according to the Cornell Feline Health Center, though splitting the daily amount into more small meals can be even better for some cats. Kittens under six months should eat about three times a day. The total daily calories matter more than the exact number of meals.
Cats are natural grazers who, in the wild, eat many tiny meals (think 8 to 10 mouse-sized snacks). That’s why some cats thrive on smaller, more frequent portions. Here’s a simple way to think about meal timing:
- Meal feeding: Set portions at set times. Best for portion control and multi-cat homes.
- Free feeding: Food left out all day. Easy, but it can lead to overeating and weight gain, so it suits only some cats.
- Puzzle and slow feeders: Make your cat work for food, which slows fast eaters and adds enrichment.
- Automatic feeders: Handy for portioned meals on a schedule when you’re busy or away.
Whatever you choose, keep the total daily calories the same. Three small meals of the right size beats two big ones if your cat begs all day or gulps and vomits.
How Do I Know If I’m Feeding My Cat the Right Amount?
You’ll know you’re feeding the right amount when your cat holds a healthy body condition: ribs you can feel easily but not see, a visible waist from above, and a slight belly tuck from the side. Vets call this a body condition score of about 5 out of 9. The scale, not the scoop, is the real report card.
This matters because so many cats carry extra weight. The Association for Pet Obesity Prevention found that 61% of US cats are overweight or obese. And the stakes are real: Cornell reports that obese cats are about four and a half times more likely to develop diabetes. Trimming portions a little can genuinely add good years to your cat’s life.
Run this quick body check every couple of weeks:
- Feel the ribs. Run your hands along your cat’s sides. You should feel ribs under a thin layer of fat, like the back of your hand. Can’t feel them? Likely overweight. Sharp and obvious? Likely underweight.
- Look from above. A healthy cat has a noticeable waist behind the ribs. A straight or bulging outline means extra weight.
- Look from the side. There should be a slight upward tuck behind the ribcage, not a sagging belly. (A loose, swinging skin flap low on the belly, called the primordial pouch, is normal and not fat.)
- Weigh monthly. Step on a scale holding your cat, then alone, and subtract. Steady weight at a healthy condition means your portions are right.
If your cat is over or under, adjust calories by about 10% and recheck in two to four weeks. Slow and steady wins. For overweight cats, never crash-diet, because rapid weight loss in cats can trigger a dangerous liver condition called hepatic lipidosis. Always plan weight loss with your vet.
Common Cat Feeding Mistakes to Avoid
The most common cat feeding mistakes all lead the same direction: too many calories. From “feeding the bag” to treats nobody counts, small habits add up to a chunky cat. Here are the big ones to sidestep.
- Feeding for current weight, not ideal weight. If your 14-pound cat should weigh 10, follow the 10-pound portion, not the 14-pound one.
- Trusting the bag’s range blindly. Label guidelines assume an average cat and often run generous. Use them as a starting point, then adjust to body condition.
- Eyeballing instead of measuring. A casual scoop can be 50% more than you think. Use a measuring cup or a gram scale.
- Forgetting treats count. Treats should stay under 10% of daily calories. That handful of crunchies adds up fast.
- Doubling wet and dry. A full bowl of each is too much. Split the calories, don’t stack them.
- Free feeding a food-motivated cat. Some cats simply can’t self-regulate, and an always-full bowl becomes a weight problem.
How Much Should I Feed My Cat in a Multi-Cat Home?
In a multi-cat home, feed each cat its own measured portion based on its own weight and needs, because a kitten, a lean adult, and a chubby senior all need different amounts. The challenge is keeping cats out of each other’s bowls. Separate feeding stations and meal feeding solve most of it.
Try these tactics when your cats have different needs:
- Feed in separate rooms or spots so a fast eater can’t poach the slow one’s food.
- Switch from free feeding to scheduled meals so you control who eats what.
- Use a microchip feeder that only opens for the right cat if one needs a special diet.
- Feed up high for the cat who needs it, since older or heavier cats may not jump, letting you separate diets by location.
Wrapping it up: figuring out how much to feed your cat comes down to three things. Know their ideal weight, aim for the right daily calories (about 20 per pound for most indoor adults), and let body condition be your guide. Get those right, measure your portions, and you’ll keep your cat lean, happy, and purring for years. When in doubt, your vet is your best teammate.
Frequently Asked Questions
Q: How much should I feed a 10-pound cat per day?
A healthy 10-pound indoor cat needs about 200 calories per day, or roughly 250 if active. That translates to about 1/3 to 1/2 cup of dry food, or two to three 3-ounce cans of wet food. Always confirm the calorie count on your specific food, since brands vary widely.
Q: How many times a day should I feed my cat?
Most adult cats do well with one or two meals a day, per the Cornell Feline Health Center, though several smaller meals can suit grazers and fast eaters. Kittens under six months need about three meals a day. What matters most is keeping the total daily calories consistent.
Q: Is it better to feed my cat wet or dry food?
Both wet and dry food can keep a cat healthy, and many vets are fine with either or a mix. Wet food adds valuable moisture and helps with fullness, while dry food is convenient, affordable, and great for puzzle feeders. The right choice depends on your cat’s health, preferences, and your routine.
Q: Am I feeding my cat too much?
You’re likely feeding too much if you can’t easily feel your cat’s ribs, there’s no visible waist from above, or the belly sags rather than tucks. With 61% of US cats overweight, overfeeding is very common. Check your cat’s body condition every couple of weeks and adjust portions by about 10% as needed.
Q: How much should I feed my kitten?
Kittens need about two to three times the calories per pound that adult cats need, fed as small, frequent meals three to four times a day. Use a food labeled for kittens or “all life stages,” since it’s richer in protein, fat, and calories. Follow the kitten food’s weight-based guidelines and adjust as your kitten grows.
Q: Should I leave food out all day for my cat?
Leaving food out all day, called free feeding, works for some cats but causes overeating and weight gain in others, according to the Cornell Feline Health Center. Food-motivated cats and multi-cat homes usually do better with measured, scheduled meals. If you free feed, only offer dry food, watch the bowl size, and monitor your cat’s weight closely.
Q: Do indoor cats need less food than outdoor cats?
Yes, indoor cats generally need fewer calories than active outdoor cats because they burn less energy. An indoor adult cat needs about 20 calories per pound of ideal weight, while an active outdoor cat may need 30 to 35. Spaying or neutering also lowers calorie needs, so most indoor, neutered cats sit at the lower end.
Q: How do I switch how much I feed my cat without upsetting their stomach?
Adjust your cat’s portion gradually, changing the daily amount by about 10% at a time and waiting two to four weeks before adjusting again. Sudden big changes in amount or a new food can cause stomach upset. If you’re switching foods too, blend the new food in over 7 to 10 days, increasing the new and decreasing the old.
