How Much Should I Feed My Cat?
Feeding a cat sounds simple, but the right answer depends on ideal weight, life stage, activity, and food calorie density. This guide gives you the practical charts and the calorie math behind them so you can stop guessing.
Fast answer
Most adult cats need about 20 kcal per pound of ideal body weight.
For a 10-pound neutered adult, that usually means about 200-240 kcal/day split into 2 meals.

The Short Answer: How Much to Feed a Cat by Weight
Before diving into the science, here is a practical reference table for healthy adult cats. These figures assume a standard commercial cat food with dry food around 350 kcal/100g, wet food around 85 kcal/100g, and a moderately active, spayed or neutered adult cat.
| Cat's Ideal Weight | Daily Calories | Dry Food / Day | Wet Food / Day | Meals / Day |
|---|---|---|---|---|
| 6 lbs (2.7 kg) | ~160 kcal | 46g (1/3 cup) | 188g (6.6 oz) | 2 |
| 8 lbs (3.6 kg) | ~200 kcal | 57g (1/2 cup) | 235g (8.3 oz) | 2 |
| 10 lbs (4.5 kg) | ~240 kcal | 69g (2/3 cup) | 282g (9.9 oz) | 2 |
| 12 lbs (5.4 kg) | ~275 kcal | 79g (3/4 cup) | 324g (11.4 oz) | 2 |
| 15 lbs (6.8 kg) | ~325 kcal | 93g (7/8 cup) | 382g (13.5 oz) | 2-3 |
Always feed based on your cat's ideal body weight, not current weight. If your cat weighs 15 lbs but should weigh 10 lbs, feed for a 10-pound cat. Feeding for the current weight of an overweight cat is one of the most common reasons cats fail to lose weight.
Calories
How Many Calories Does a Cat Actually Need?
The 20 Calories Per Pound Rule, and Why It Is Just a Starting Point
Adult cats are often estimated at about 20 calories per pound of body weight per day. For a 10-pound cat, that is around 200 calories. It is a useful ballpark, but it treats a sedentary neutered indoor cat the same as an active intact cat.
The RER Formula: More Accurate for Individual Cats
Veterinary nutrition calculations commonly start with Resting Energy Requirement, or RER. The formula is:
For a 10-pound cat, or about 4.5 kg, RER is approximately 216 kcal/day. To estimate daily energy requirement, multiply RER by the right life-stage factor.
| Life Stage | Multiplier | Example for 10 lb cat |
|---|---|---|
| Kitten < 4 months | x 3.0 | ~648 kcal/day |
| Kitten 4-12 months | x 2.5 | ~540 kcal/day |
| Intact adult | x 1.4 | ~302 kcal/day |
| Neutered adult | x 1.2 | ~259 kcal/day |
| Inactive / obese-prone | x 1.0 | ~216 kcal/day |
| Active adult | x 1.6 | ~346 kcal/day |
| Pregnant | x 2.0 | ~432 kcal/day |
| Nursing | x 2.5 | ~540 kcal/day |
Life stage
Cat Feeding Chart: How Much to Feed by Age and Life Stage
How Much to Feed a Kitten
Kittens grow from a few ounces to nearly full adult size in the first year, so they need much more energy per pound than adult cats.
| Kitten Age | Weight | Daily Calories | Dry Food / Day | Wet Food / Day | Meals / Day |
|---|---|---|---|---|---|
| 6-8 weeks | 0.5-1 lb | 100-150 kcal | 30-43g | 118-176g | 4 |
| 2-3 months | 1.5-3 lbs | 200-280 kcal | 57-80g | 235-329g | 4 |
| 3-6 months | 3-5 lbs | 280-400 kcal | 80-114g | 329-471g | 3-4 |
| 6-12 months | 5-8 lbs | 320-480 kcal | 91-137g | 376-565g | 3 |
Key kitten feeding rules
- Never restrict a kitten's calories unless directed by a veterinarian.
- Feed kitten-specific food until 12 months because it is higher in protein and calorie density.
- Transition to adult food gradually over 7-10 days at the 12-month mark.
How Much to Feed an Adult Cat
The adult stage is usually the most stable nutritionally. The main variables are neuter status, activity level, and body condition.
| Weight | Neutered / Indoor | Intact / Active | Meals / Day |
|---|---|---|---|
| 8 lbs (3.6 kg) | ~195 kcal | ~240 kcal | 2 |
| 10 lbs (4.5 kg) | ~240 kcal | ~300 kcal | 2 |
| 12 lbs (5.4 kg) | ~275 kcal | ~345 kcal | 2 |
| 15 lbs (6.8 kg) | ~325 kcal | ~410 kcal | 2-3 |
The single biggest mistake adult cat owners make is following bag guidelines without adjustment. Those guidelines often skew toward active, intact cats. A neutered indoor cat may need 15-20% less than the package suggests.
How Much to Feed a Senior Cat
Senior cats are nuanced. Ages 7-11 may have slightly slower metabolism, while cats over 11 often lose weight and muscle mass and may need more calories with high-quality protein.
| Weight | Age 7-11 | Age 11+ | Meals / Day |
|---|---|---|---|
| 8 lbs | ~185 kcal | ~200 kcal | 2-3 |
| 10 lbs | ~230 kcal | ~250 kcal | 2-3 |
| 12 lbs | ~265 kcal | ~285 kcal | 3 |
Special cases
Overweight, Pregnant, and Nursing Cats
How Much to Feed an Overweight Cat
If your cat weighs 15 lbs but their ideal weight is 10 lbs, calculate portions for the 10-pound cat. Feeding for current overweight body mass maintains obesity instead of creating a weight-loss plan.
Safe weight loss for cats is no more than 0.5-1% of body weight per week. Never cut calories by more than 20-25% at once because rapid restriction can cause hepatic lipidosis, a potentially fatal fatty liver disease. Always consult your veterinarian before starting a weight-loss plan.
Overweight cat feeding formula
- Determine ideal body weight with a body condition score check.
- Calculate RER for ideal weight.
- Multiply by 1.0 as a weight-loss factor.
- Split that amount into 2-3 measured meals.
How Much to Feed a Pregnant or Nursing Cat
Pregnant cats often need 25-50% more calories as pregnancy progresses. Nursing cats can need 2-2.5 times normal calories, which is the highest energy demand of a cat's life. Switch to kitten food during pregnancy and nursing to support both mother and kittens.
Dry food
How Much Dry Food Should I Feed My Cat?
Dry food is calorie-dense, ranging from about 300 kcal/cup for light formulas to 500 kcal/cup for dense high-protein foods. For a 10-pound neutered adult cat needing 240 kcal/day, the right amount changes sharply by brand.
| Food Type | Kcal/100g | Daily Amount |
|---|---|---|
| Light/weight management dry | 280 kcal | 86g (3/4 cup) |
| Standard dry food | 350 kcal | 69g (2/3 cup) |
| High-protein dry food | 430 kcal | 56g (1/2 cup) |
| Dense grain-free dry | 500 kcal | 48g (2/5 cup) |
Use a kitchen scale or a proper measuring cup. A gram scale is more accurate than a cup because kibble density varies by shape and size.
Wet food
How Much Wet Food Should I Feed My Cat?
Wet food is much lower in calorie density, commonly 70-100 kcal per 3-ounce can. Cats need more volume of wet food to meet the same calorie target.
| Wet Food Type | Kcal/100g | Daily Amount | Equivalent |
|---|---|---|---|
| Low-calorie pate | 70 kcal | 343g | ~4 x 3-oz cans |
| Standard wet food | 85 kcal | 282g | ~3.3 x 3-oz cans |
| Dense wet food | 100 kcal | 240g | ~2.8 x 3-oz cans |
Wet food advantages
- Hydration support because wet food is usually 75-82% water.
- Weight management because lower calorie density creates larger portions for the same calories.
- Urinary health support through higher moisture intake.
- Senior cat support because wet food is easier to chew and digest.
Remove uneaten wet food after 20-30 minutes at room temperature. Refrigerate opened cans and use within 24-48 hours.
Mixed feeding
Mixing Wet and Dry Food: How Much of Each?
Mixed feeding works when calories from both foods combined equal your cat's daily calorie target. For a 10-pound neutered adult cat needing 240 kcal/day, common splits look like this:
| Feeding Split | Dry Food | Wet Food |
|---|---|---|
| 25% dry / 75% wet | 17g (1/6 cup) | 212g (7.5 oz) |
| 50% dry / 50% wet | 34g (1/3 cup) | 141g (5 oz) |
| 75% dry / 25% wet | 51g (1/2 cup) | 71g (2.5 oz) |

How Often Should I Feed My Cat?
Kitten Feeding Schedule
Young kittens have small stomachs and high energy needs. Under 3 months, plan on 4 meals per day. From 3-6 months, use 3-4 meals. From 6-12 months, 3 meals per day is common.
Adult Cat Feeding Schedule
Most adult cats do well on 2 measured meals per day, spaced 8-12 hours apart. A simple schedule is half the food at 7:00 AM and half at 6:00 PM.
Free Feeding vs. Scheduled Meals
Free feeding can work for cats who self-regulate, but scheduled meals give you portion control, make appetite changes easier to notice, and make weight management far easier. Very young kittens and nursing mothers are the main exceptions.
Body condition
Signs Your Cat Is Getting Too Much or Too Little Food
5 signs you're feeding too much
- You cannot feel the ribs with light pressure.
- There is no visible waist from above.
- The abdominal pouch visibly sways while walking.
- Your cat is lethargic and uninterested in play.
- Your cat finishes food instantly and immediately begs for more.
5 signs you're not feeding enough
- Ribs, spine, or hip bones are visible.
- The coat looks dull, dry, or rough.
- Vocalization around meals becomes urgent and persistent.
- Energy and play interest drop.
- Your cat loses weight over time.
Mistakes
The 5 Most Common Cat Feeding Mistakes
Mistake 1
Feeding for current weight instead of ideal weight
If an overweight cat weighs 15 lbs, feeding the 15-pound portion maintains the excess weight.
Mistake 2
Eyeballing portions
About this much is not a measurement. Use a kitchen scale or measuring cup every time.
Mistake 3
Ignoring calorie density differences
A cup of one food may be 320 kcal while another is 480 kcal. Always check the kcal per unit.
Mistake 4
Not counting treats
Treats should make up no more than 10% of daily calories.
Mistake 5
Switching foods abruptly
Transition over 7-10 days with gradually increasing amounts of the new food.
Food labels
How to Read Feeding Guidelines on Cat Food Packaging
Package guidelines are based on an average cat, often an active intact adult. Treat them as a starting point, not a personalized target.
Use the label correctly
- Find kcal/cup, kcal/can, or kcal/kg on the label.
- Calculate your cat's daily calorie target.
- Divide target calories by kcal per unit.
- Split the result into 2-3 measured meals.
Vet guidance
When to Consult Your Veterinarian About Feeding
Most healthy cats do well on standard commercial cat food in appropriate amounts. Consult your vet if:
- Your cat is losing weight despite eating normally.
- Your cat is gaining weight despite eating the calculated amount.
- Your cat refuses food for more than 24 hours as a kitten or 48 hours as an adult.
- Your cat has kidney disease, diabetes, urinary issues, or IBD.
- You want to put your cat on a weight-loss plan.
FAQ
Frequently Asked Questions
How much should I feed my cat per day?
Most adult cats need approximately 20 calories per pound of ideal body weight per day. A healthy 10-pound neutered adult cat needs roughly 200-240 calories daily, or about 2/3 cup of standard dry food or 3-3.5 small cans of wet food split into two meals.
How many times a day should I feed my cat?
Kittens under 6 months usually need 3-4 meals per day, adult cats usually do well with 2 meals per day, and senior cats may benefit from 2-3 smaller meals per day.
Is it OK to leave dry cat food out all day?
Dry food is shelf-stable at room temperature, but free-choice dry feeding can increase obesity risk. Measured scheduled meals make it easier to control calories and notice appetite changes.
How much should I feed an overweight cat?
Feed based on ideal body weight, not current body weight. Reduce calories gradually, avoid cuts greater than 20-25% at once, aim for no more than 0.5-1% body weight loss per week, and work with a veterinarian.
How do I know if I'm feeding my cat the right amount?
Use body condition score and monthly weighing. You should feel ribs with light pressure but not see them, see a waist from above, and see a slight abdominal tuck from the side.
Should I feed my cat wet food, dry food, or both?
Both can be nutritionally complete. Wet food improves moisture intake and can help weight management, while dry food is convenient and cost-effective. Many cats do well with a measured mix of both.
How much wet food equals how much dry food?
Because wet food contains much more water, equivalent portions must be calculated by calories, not by weight or volume. Roughly, 1/3 cup of dry food is close to 1.5 small cans of wet food, depending on each product's calorie label.
The bottom line
Use numbers, then watch the cat in front of you.
- Feed based on ideal body weight, not current weight.
- Use the RER formula for a more accurate calorie target.
- Measure portions and check your food's calorie density.
- Keep treats under 10% of daily calories.
- Weigh your cat monthly and adjust gradually.
