How much wet food should I feed my cat?
Pouches make portioning feel easy — until you realize a "pouch" is a packaging size, not a nutrition unit. Here's the actual math, in pouches, so you can feed with confidence.
The pouch math
A standard 85 g pouch delivers roughly 65–90 kcal depending on the recipe (the exact figure is on the label — in the EU usually as kcal or kJ per 100 g). Match that against your cat's daily calorie need and the answer falls out. For typical neutered adults on wet food only:
| Cat's weight | Approx. kcal/day | 85 g pouches/day |
|---|---|---|
| 3 kg (6.6 lb) | ~190 | ~2.5–3 |
| 4 kg (8.8 lb) | ~240 | ~3–3.5 |
| 5 kg (11 lb) | ~280 | ~3.5–4 |
| 6 kg (13 lb) | ~320 | ~4–4.5 |
Yes — that's more pouches than many feeding habits assume, which is exactly why cats fed "two pouches plus some biscuits" often drift in whichever direction the unmeasured biscuits decide.
Mixed feeding: budget calories, not bowls
Most households feed both. The reliable method: set the daily kcal target, subtract what the wet food provides, and weigh out only enough dry to cover the remainder. Example for a 240 kcal cat: two pouches (~140 kcal) leaves ~100 kcal — about 27 g of a 375 kcal/100 g kibble. Not the half-cup the scoop wants to pour: dry food is so calorie-dense that "a little topping" is where mixed feeding quietly fails.
Why wet food earns its mess
Wet food is ~78% water, and cats have a famously weak thirst drive — they evolved getting moisture from prey. A wet-fed cat drinks visibly little from the bowl and that's normal (our water calculator shows the split). The hydration boost is also why wet food often features in urinary-health conversations with vets.
Practical wet-food habits: serve at room temperature (fridge-cold food is widely snubbed), cover and refrigerate opened portions and use within about 24 hours, and lift uneaten wet food after 1–2 hours in warm weather.
Frequently asked questions
How many pouches for a 4 kg cat?
About 3–3.5 standard 85 g pouches on wet-only feeding, or commonly 1–2 pouches plus a weighed dry portion in mixed feeding. Check your pouch's kcal — recipes range 65–90.
Is wet-only feeding okay long term?
Yes, provided the food says "complete" on the label ("complementary" foods are toppers, not full diets). Wet-only also maximizes water intake, which suits many cats well.
My cat begs constantly on this amount — am I starving it?
If ribs are easy to feel and there's a visible waist, the portion is right and the performance is theater. Splitting the day into 3–4 servings and using puzzle feeders makes the same calories feel like more.
