HOW MUCH SHOULD YOU FEED A CAT? A SIMPLE PORTION GUIDE FOR HEALTHY CATS
Knowing how much to feed a cat is one of the most common — and most confusing — questions cat owners ask.
Feed too little and your cat may lose weight, lack energy, or miss essential nutrients. Feed too much and you risk obesity,
diabetes, joint problems, and a shorter lifespan.
This simple portion guide breaks down exactly how much to feed your cat based on weight, age, food type, and lifestyle. It’s designed to be easy to follow, SEO-friendly, and helpful whether you’re feeding dry food, wet food, or a mix of both.
WHY PORTION CONTROL MATTERS FOR CATS
Cats are obligate carnivores with specific nutritional needs. Unlike dogs, they don’t self-regulate calories well — especially indoor cats.
Modern pet food is calorie-dense, and even small overfeeds can add up quickly.
Proper portion sizes help:
• Maintain a healthy weight
• Support muscle mass
• Prevent diabetes and urinary issues
• Improve energy and coat health
• Extend your cat’s lifespan Portion control is not about restricting food — it’s about feeding the right amount consistently.
HOW MANY CALORIES DOES A CAT NEED PER DAY?
Most adult cats need between 20–25 calories per pound of body weight per day, depending on activity level and metabolism.
General daily calorie estimates:
• 8 lb cat: 160–200 calories/day
• 10 lb cat: 200–250 calories/day
• 12 lb cat: 240–300 calories/day
These numbers apply to average, neutered indoor cats. Highly active or outdoor cats may need slightly more, while senior or sedentary cats may need less.
HOW MUCH DRY FOOD SHOULD YOU FEED A CAT?
Dry food is calorie-dense, so portion sizes are smaller than many owners expect.
Typical dry food portions:
• 8–10 lb cat: ¼ to ½ cup per day
• 10–12 lb cat: ½ to ⅔ cup per day
Always check the calorie content on the bag. Some dry foods contain 300 calories per cup, while others contain over 450 calories per cup. Measuring with a real measuring cup — not eyeballing — is critical.
Most cats eating dry food need about ¼–½ cup per day, depending on calorie density and body weight.
HOW MUCH WET FOOD SHOULD YOU FEED A CAT?
Wet food contains more moisture and fewer calories per ounce, making portion sizes larger.
Typical wet food portions:
• 8–10 lb cat: 2½ to 3 standard 3-ounce cans per day
• 10–12 lb cat: 3 to 4 cans per day
Wet food supports hydration and urinary health, especially for indoor cats.
Most adult cats need about 2–4 small cans of wet food per day, depending on size and activity.
MIXED FEEDING: COMBINING WET AND DRY FOOD
Many owners use a mixed feeding approach. The key is to balance calories — not portions.
Example mixed feeding plan for a 10 lb cat:
• Morning: 1 can wet food (90 calories)
• Evening: ¼ cup dry food (110 calories)
Total: ~200 calories per day
Never feed full portions of both wet and dry without adjusting amounts — this is a common cause of overfeeding.
FEEDING GUIDELINES BY LIFE STAGE
KITTENS (UP TO 12 MONTHS)
Kittens need more calories for growth.
• Feed 3–4 meals per day
• Free-feeding is acceptable for young kittens
• Choose kitten-specific food
Kittens may need double the calories of an adult cat per pound of body weight.
ADULT CATS (1–7 YEARS)
Adult cats do best on:
• 2 measured meals per day
• Consistent portions
• Stable calorie intake
Avoid constant grazing if weight gain is a concern.
SENIOR CATS (7+ YEARS)
Senior cats may need:
• Slightly smaller portions
• Higher protein foods
• More frequent but smaller meals
Weight loss in seniors should always be discussed with a veterinarian.
HOW TO TELL IF YOU’RE FEEDING TOO MUCH OR TOO LITTLE
Signs of overfeeding:
• Weight gain
• Lethargy
• Difficulty grooming
• Visible belly sag
Signs of underfeeding:
• Rib visibility
• Muscle loss
• Constant hunger
• Low energy
You should be able to feel your cat’s ribs easily but not see them prominently.
HOW OFTEN SHOULD YOU FEED A CAT?
Most adult cats do best with:
• Two meals per day, 10–12 hours apart
Some cats prefer:
• Three smaller meals
• Timed feeders for dry food
Consistency matters more than frequency.
Most adult cats should be fed two measured meals per day for optimal weight control.
COMMON CAT FEEDING MISTAKES TO AVOID
• Guessing portion sizes instead of measuring
• Feeding based on bowl size instead of calories
• Overfeeding treats (treats should be under 10% of daily calories)
• Free-feeding dry food for indoor cats
• Ignoring weight changes
Even small daily overfeeds can lead to pounds gained over time.
SHOULD YOU ADJUST PORTIONS OVER TIME?
Yes. Cats are not static.
Adjust portions if:
• Your cat gains or loses weight
• Activity level changes
• You switch food brands
• Your cat ages into a new life stage
Recheck your cat’s weight every 1–2 months and adjust gradually.
SIMPLE CAT FEEDING PORTION SUMMARY
Quick reference:
• Most cats need 20–25 calories per pound per day
• Dry food: ~¼–½ cup daily
• Wet food: ~2–4 small cans daily
• Measure every meal
• Adjust based on weight and activity
FINAL THOUGHTS
Feeding the right amount is one of the most powerful ways to protect your cat’s health. With proper portions, consistent meals, and calorie awareness, you can help your cat maintain a healthy weight, better energy levels, and a longer life.
If you’re ever unsure, start with the calorie guidelines above and adjust slowly. Portion control doesn’t mean less love — it means better care.
