How Much Should You Feed Your Cat?

How Much Should You Feed Your Cat?

Wet and dry cat food can't be measured on the same scale — dry food is calorie-dense (typically 300-400 kcal per cup) while canned wet food is much less concentrated (often under 100 kcal per 3 oz can) due to its high moisture content, so a chart that just says "X cups" without specifying food type will be wrong for half of readers. This chart breaks portions out separately for dry-only, wet-only, and mixed-feeding households, cross-referenced against your cat's weight and life stage, since kittens need roughly 2-3x the calories per pound of an adult cat during peak growth.

How to use this calculator

Enter your cat's weight, life stage, food type (dry, wet, or mixed), and the calorie density from your food's label. Portions are calculated separately by food type since dry and wet food differ roughly 3–4x in calorie density per volume.

Understanding your results

If you're mixing wet and dry, don't feed full portions of both — calculate the calories coming from whichever food makes up most of the diet, then fill the remaining daily target with the other type, rather than treating each portion as independent. Bag and can feeding guidelines tend to run generous industry-wide, so if your cat is gaining weight at the "recommended" amount, that's a normal reason to feed less than the label suggests, not a sign something's wrong with your cat.

Why meal frequency matters, not just total calories. Kittens have small stomachs and high energy needs relative to size, which is why they need more frequent, smaller meals rather than the same total calories split into two large adult-style meals — free-feeding dry food is common for kittens specifically for this reason, with portions still tracked against a daily target.

Multi-cat households need per-cat tracking, not a shared bowl total. If cats free-feed from a shared bowl, it's hard to know if one cat is eating significantly more than its share — separate feeding stations or supervised meals make individual portion tracking possible, which matters especially if one cat needs a different calorie target than another.

Reading your specific food's label instead of relying on averages

The portion figures in this chart use commonly cited average calorie densities, but actual pet food varies enough between brands and formulas that checking your specific food's label is what turns a rough chart into an accurate portion. Dry food calorie density can range from roughly 300 to over 500 kcal per cup depending on the formula, and wet food varies similarly by brand and moisture content — a portion calculated from this chart's average figures could be meaningfully off for a food on either end of that range. If your food's label lists "kcal/kg" rather than "kcal/cup" or "kcal/can," that's still usable, but it requires converting using the total weight of a cup or can of that specific product, which is more precise than assuming a generic conversion applies. When in doubt, the Cat Food Calculator tool on this site walks through that conversion using your exact food's label figures rather than the average density this chart assumes.

Adjusting portions as circumstances change

The portions in this chart represent a starting point for a healthy cat at a stable weight and typical activity level, and several common situations call for a deliberate adjustment rather than sticking rigidly to the chart figure. A cat recovering from illness or surgery may temporarily need a different feeding approach entirely (sometimes more frequent, smaller meals, or a prescription recovery diet) under your vet's specific guidance rather than the standard maintenance chart. A cat that's recently been spayed or neutered typically sees a modest drop in metabolic rate, which means the same portion that maintained weight before surgery can lead to gradual gain afterward if not adjusted down slightly. And for any cat trending away from a healthy weight in either direction over a few consecutive weigh-ins, the chart's starting portion should be treated as the number to adjust from based on that trend, not a fixed target to defend regardless of how your specific cat is actually responding to it.
