How Much Should I Feed My Indoor Cat Per Day?
If you’ve ever poured food into your cat’s bowl and immediately been stared at like you’ve committed a personal crime, welcome.
I've been there. Indoor cats are absolute masters of making “I can see the bottom of the bowl” feel like a felony.
But here’s the thing: feeding your cat the right amount isn't about how dramatic they are (and oh, they are dramatic).
It’s about calories, body condition, and the fact that many indoor cats are living a pretty sweet, low-step-count lifestyle.
Think less “tiny jungle predator,” more “soft manager of the living room ottoman.”
So, how much should I feed my indoor cat per day?
For most healthy indoor adult cats, a solid starting point is:
About 20–35 kcal per pound of ideal body weight per day
Or around 40–45 kcal per kilogram of ideal body weight per day
For many typical indoor cats, that lands somewhere around:
180–250 calories per day for a 9–11 lb (4–5 kg) cat
That’s the short answer.
The real answer is a little more annoying—is he doing this on purpose?!—because it depends on the food, your cat’s age, and whether they spend the day zooming or sleeping in a bread loaf shape on a windowsill.
Let’s break it down in a way that doesn’t make you want to throw the measuring cup into the sea.
By the way, if you'd love more affection from your cat, I created a 15 minute tool that turned my own distant cat into my shadow!
Why Indoor Cats Usually Need Less Food Than You Think
Indoor cats usually burn fewer calories than outdoor cats. They’re not scaling fences or living a high-stakes action movie.
They’re mostly walking from the couch to the food bowl and then back to the couch like tiny, elegant retirees.
That means they often need less food than the package suggests.
A lot of feeding labels are broad starting points, not commandments carved into stone.
And for strictly indoor, neutered adult cats, those guidelines can be a bit generous. It's so easy to overfeed without even realizing it!
One of the biggest mistakes I see is feeding based on a cat’s current weight instead of their ideal weight.
If your cat is already overweight, using the higher number just keeps the cycle going.
How Much Should I Feed My Indoor Cat Per Day Based on Weight?
Here are some practical starting ranges for healthy indoor adult cats:
3 kg (6.5 lb) indoor cat
About 130–180 kcal per day
If eating dry food with 450 kcal per cup: roughly 0.3–0.4 cup per day
4 kg (9 lb) indoor cat
About 160–220 kcal per day
That’s roughly 0.35–0.5 cup per day of a dry food with 450–500 kcal per cup
Or about 2–3 small wet cans, depending on the calorie content
5 kg (11 lb) indoor cat
About 200–250 kcal per day
This is a very common range for the average indoor adult cat
These are starting points, not perfect forever numbers. Your cat did not read this, so they will definitely have their own opinions.
How to Turn Calories Into Actual Food
This is the part people skip, and it’s where most of the confusion starts. Your cat does not eat “calories.”
Your cat eats kibble, pâté, or that one expensive food they loved for six days and now reject with deep contempt. The ultimate betrayal!
Once you know your cat’s daily calorie target, check the label on the food for:
kcal per cup for dry food
kcal per can or pouch for wet food
Then use this simple formula:Daily calorie target ÷ calories in the food = how much to feed per day
Example: Dry food
Let’s say your indoor cat needs 200–250 kcal per day.
If the dry food has 500 kcal per cup, then:
200 ÷ 500 = 0.4 cup
250 ÷ 500 = 0.5 cup
So your cat should get about 0.4–0.5 cup per day, not a heaping, unhinged bowlful.
Example: Wet food
If your cat needs about 200 kcal per day, and each small can contains 70–100 kcal, then your cat may need around 2–3 small cans per day.
Dry Food Is Sneakily Calorie-Dense
This deserves its own section because dry food is often the reason a cat gains weight while still acting personally starved.
Are you kidding me?! Many dry foods contain 400–500+ calories per cup. Even a little extra each day adds up fast.
Suddenly your cat has entered what we’ll politely call their “extra cuddly era.”
For better accuracy:
Use a kitchen scale if you can
Measure in grams, not just cups
Pre-portion the full day’s food so everyone in the house knows what the cat already got
Because yes, your cat will absolutely run a multihousehold scam if given the chance.
Wet vs. Dry: Which Is Better for Portion Control?
Both can work. The best choice often depends on your cat’s preferences and your budget. But in terms of portioning, wet food can be easier because cans feel more concrete.
Dry food is more concentrated, so small overpours matter more.
A mixed diet can also work well, as long as you count the calories from both. The key word here is measured. Not “vibes.” Not “until my cat looked pleased.”
How Often Should You Feed an Indoor Cat?
For years, we heard that cats should eat lots of tiny meals because that matches natural hunting patterns.
In theory, your cat is a graceful mini predator. In practice, your cat may be hunting dust.
Recent research suggests that feeding adult indoor cats once a day may actually make them feel fuller.
Cats fed one larger meal showed stronger satiety signals and less food-seeking behavior between meals.
That does not mean once-daily feeding is the magic answer for every cat. For many homes, two meals a day (morning and evening) is still a very practical sweet spot.
It’s simple and less chaotic than free-feeding.
Why Free-Feeding Often Backfires
Free-feeding sounds convenient, but many indoor cats treat it like an all-day brunch cruise. Leaving dry food down all day can encourage boredom eating and turn your cat into a highly persuasive snack lobbyist.
If your cat seems obsessed with food, don’t assume they need more calories right away. Sometimes they just need more play or puzzle feeders.
Sometimes your cat is not hungry—sometimes your cat is bored and has chosen food as a hobby.
Don’t Forget Treat Calories
Treats count. Painfully, unfairly, and completely. A good rule: Treats should be no more than 10% of your cat’s daily calories.
If you hand out treats like confetti, you have to reduce the main meal. Otherwise, your cat is basically eating dinner plus a snack budget that would impress a college freshman.
How to Tell If You’re Feeding Too Much or Too Little
The food bowl is not the best judge. Your cat is definitely not the best judge. Their testimony is biased. Instead, watch body condition.
A healthy cat should have ribs you can feel but not clearly see and a visible waist from above.
Signs you may be feeding too much
Gradual weight gain or increased roundness
Your cat seems less active
Signs you may be feeding too little
Ribs or spine becoming too obvious
Persistent hunger plus loss of condition
If anything changes significantly, check with your vet instead of playing food detective for six months.
A Simple Step-by-Step Feeding Plan
Here’s a way to figure this out without a spreadsheet and a nervous breakdown:
Start with ideal body weight: Feed for the weight they should be.
Read the label: Find the kcal per cup or can.
Do the math: Daily calorie target ÷ food calories = daily amount.
Split it into meals: 1 or 2 meals a day usually works best.
Keep treats under control: Aim for less than 10% of daily calories.
Recheck every 2–4 weeks: Watch their waist and energy level.
The Biggest Feeding Mistakes Indoor Cat Owners Make
Let’s save you some trouble:
Trusting the bag like it’s sacred text: Those are just starting points.
Using the wrong weight: Don't feed for an overweight status.
Free-pouring dry food: This is how “just a little extra” turns into a lot.
Forgetting treats exist: They count, even if your cat insists they are emotionally necessary.
Why Getting This Right Matters
I love cats like I love my right arm and both of my kidneys, and that's why this matters.
Overfeeding is so common, and the risks—like diabetes and joint pain—are real.
On the flip side, cats should never crash diet. If they lose weight too fast, they can develop serious liver problems.
Final Answer: How Much Should I Feed My Indoor Cat Per Day?
For most healthy indoor adult cats, start with 20–35 kcal per pound of ideal body weight. For the average cat, that's around 180–250 calories per day.
The goal isn't to win your cat’s approval. That was never on the table. The goal is to keep them healthy, comfortable, and ideally just dramatic enough to remain entertaining.
If your cat is currently standing near the bowl acting like they haven’t eaten since the Great Depression, stay strong. You are a flipping fantastic cat parent. <3
