Feeding your cat the right amount of food is one of the most important decisions you make as a pet owner. Proper feeding supports your cat’s energy levels, body weight, immunity, digestion, coat quality, and overall long-term health. However, knowing how much food to feed a cat can be confusing because the answer depends on multiple factors such as age, weight, activity level, health status, and the type of food you use.
This in-depth guide breaks down how much to feed your cat, how to read pet food labels, how to adjust portions based on your cat’s needs, and common feeding mistakes to avoid. By the end, you’ll have all the information you need to create a healthy, sustainable feeding routine that works for your feline companion.
Why the Right Amount of Food Matters
Feeding your cat the correct amount is essential because both overfeeding and underfeeding can lead to health complications.
The Risks of Overfeeding
A significant number of indoor cats are overweight or obese. Overfeeding can lead to:
- Excess body fat
- Diabetes
- Joint stress and arthritis
- Heart strain
- Difficulty grooming
- Shortened lifespan
Even an extra tablespoon of food a day can slowly lead to noticeable weight gain over time.
The Risks of Underfeeding
On the other hand, underfeeding can cause:
- Nutrient deficiencies
- Weight loss
- Lethargy
- Reduced immunity
- Poor skin and coat health
- Organ stress
This is why finding the right portion size is so important—and it starts with understanding your cat’s nutritional needs.
How Much Should I Feed My Cat? General Guidelines
The first step in determining how much to feed your cat is understanding that there is no single universal amount. However, general guidelines can help you get started.
Typical Daily Calorie Requirements for Cats
On average, a healthy adult cat needs:
- 20 calories per pound of body weight per day (as a baseline)
So, if your cat weighs 10 pounds, they need about 200 calories a day.
This is only a starting point. Many factors change a cat’s calorie needs.
Daily Calories Based on Life Stage
Different life stages require different feeding amounts.
Kittens (Under 1 Year Old)
Kittens need two to three times the calories of an adult cat because they are growing rapidly.
- 60–70 calories per pound of body weight
- 3–4 meals per day
They should be fed kitten-specific food, which is more calorically dense.
Adult Cats (1–7 Years)
Most adult cats need:
- 20–30 calories per pound
- 2 meals per day
More active cats may need more; sedentary cats may need less.
Senior Cats (7+ Years)
Senior cats often have slower metabolisms and reduced activity. However, some seniors actually need more calories, depending on muscle condition and underlying health.
Most seniors need:
- 20–25 calories per pound
- Easily digestible food
- More moisture (wet food is recommended)
Consult your veterinarian for individualized guidance.
Wet Food vs. Dry Food: How It Affects Portion Size
Your cat’s food type significantly impacts how much you should feed.
How Much Dry Food to Feed a Cat
Dry food (kibble) is calorie-dense and concentrated.
Typical dry food contains:
- 300–400 calories per cup
- 60–100 calories per ¼ cup
This means portion sizes are small. Many owners accidentally overfeed because kibble seems like “too little” in the bowl.
How Much Wet Food to Feed a Cat
Wet food has fewer calories per ounce because it contains moisture.
Typical wet food contains:
- 70–120 calories per 3-ounce can
- 140–200 calories per 5.5-ounce can
Most adult cats require:
- One 5.5-ounce can per day, OR
- Two 3-ounce cans per day
However, brands vary, so always check calories on the label.
Combination Feeding (Wet + Dry)
Many cat owners use a mix of both wet and dry food to maintain hydration, palatability, and convenience.
A common combination:
- 1 small can of wet food
- 1/8 to 1/4 cup dry food
This can be ideal for cats who enjoy variety or who benefit from both textures.
How to Read a Cat Food Label for Feeding Amounts
Most cat food bags and cans include feeding guidelines, but many owners misunderstand them.
Here’s what you should look for:
Check the Calorie Content
Labels should list:
- Calories per cup (dry food)
- Calories per can or ounce (wet food)
You cannot accurately feed your cat without knowing this number.
Use the Label as a Starting Point—Not a Final Rule
Feeding guidelines are estimates based on ideal weight and average activity. If your cat is less active than average, feeding label amounts may cause weight gain.
Adjust Based on Your Cat’s Body Condition
If your cat is:
- Overweight: feed 10–20% less
- Underweight: feed 10–20% more
- Perfect weight: maintain the current amount
Use body condition scoring charts to guide adjustments.
How Often Should I Feed My Cat?
Feeding frequency matters almost as much as portion size.
Two Meals per Day (Most Common)
Most adult cats do best with:
- Morning meal
- Evening meal
This creates a predictable routine and helps you monitor appetite—an early indicator of health issues.
Free Feeding (Not Recommended for Many Cats)
Leaving food out all day can work for some cats, but for others it leads to overeating and obesity. This is especially problematic with dry food due to its calorie density.
Free feeding is not recommended for overweight cats or multi-cat households.
Three or More Meals (Helpful for Certain Cats)
More frequent meals help:
- Kittens
- Elderly cats
- Cats with sensitive stomachs
- Cats with diabetes
- Cats who vomit from hunger
Portions should be reduced per meal but distributed throughout the day.
How Your Cat’s Weight Affects How Much You Should Feed
Your cat’s ideal weight guides how much food you should provide.
For Underweight Cats
If your cat is underweight:
- Increase calories gradually
- Offer calorie-dense wet food
- Feed smaller, more frequent meals
- Check for health issues (hyperthyroidism, parasites)
For Overweight Cats
If your cat is overweight:
- Reduce daily calories by 10–20%
- Increase meal frequency
- Add more wet food (lower calorie density)
- Avoid treats or keep them under 10% of daily calories
- Increase activity with play sessions
Never starve or crash-diet a cat—this can cause fatty liver disease, a life-threatening condition.
For Ideal-Weight Cats
Maintain weight by:
- Sticking to consistent meal portions
- Monitoring appetite and energy
- Weighing your cat weekly or monthly
Subtle weight changes can signal health issues early.
Special Factors That Change How Much a Cat Should Eat
Activity Level
Active cats need more calories than sedentary indoor cats.
Energetic breeds like Bengals or Abyssinians may require additional food.
Indoor vs. Outdoor Lifestyle
Outdoor cats burn more energy through:
- Exploration
- Climbing
- Hunting
They may need 10–30% more calories.
Health Conditions
Certain health issues dramatically affect feeding amounts.
Cats with:
- Diabetes: need consistent meals
- Kidney disease: benefit from lower-protein, higher-moisture diets
- Thyroid disease: may need more calories
- Digestive disorders: require specific diets
Always consult your veterinarian if your cat has a medical condition.
Spayed and Neutered Cats
Fixed cats have lower energy needs and often require:
- 20–30% fewer calories
This is why many cats gain weight after being spayed or neutered.
Tools to Help You Feed the Right Amount
Measuring Cups
Always use a real measuring cup—not an estimate. Eye-balling kibble leads to overfeeding.
Kitchen Scale
Weighing wet food (in grams) ensures precise feeding.
Automatic Feeders
Great for:
- Creating controlled portioning
- Feeding multiple small meals
- Helping cats with strict diets
Food Diaries or Apps
Tracking meals can prevent accidental double-feeding.
Sample Feeding Guidelines Based on Weight
These general examples assume:
- An average indoor adult cat
- No health issues
- Regular exercise
- Standard-calorie wet and dry foods
For a 5-pound Cat
- 100–150 calories per day
- About 1/3–1/2 can of wet food + small amount of kibble
For a 10-pound Cat
- 200 calories per day
- 1 full 5.5-ounce can of wet food
- Or 1/4 to 1/3 cup dry food
For a 15-pound Cat (needs weight check)
Cats at 15 pounds are often overweight unless they are large breeds like Maine Coons.
- 220–250 calories per day
- More wet food, less kibble recommended
Adjust based on body condition.
Common Feeding Mistakes Cat Owners Make
Free Feeding Too Much Dry Food
This is the #1 cause of indoor-cat obesity.
Ignoring Treat Calories
Treats should be less than 10% of daily intake.
Feeding Human Food
Some human foods are toxic, and others can cause digestive issues.
Not Adjusting Portions as Cats Age
Older or less active cats need fewer calories.
Using Cups Instead of Grams for Wet Food
Wet food is more accurate when weighed.
How to Tell If You’re Feeding the Right Amount
Watch for signs in your cat:
