Quick answer
An adult cat eats 40–60 grams of dry food per day per 4 kg of body weight. Kittens need relatively more, older cats slightly less. Most packaging underestimates the portion: use your cat's weight as the starting point, not the recommendation on the bag.
De meeste katteneigenaren vullen de bak "op gevoel" bij. Begrijpelijk, maar het leidt tot twee problemen: te weinig eten (ondergewicht, traagheid) of te veel eten (overgewicht, gewrichtsklachten). Katten zijn kleine dieren met een nauwkeurig voedingsritme. Een portieverschil van 10 gram per dag heeft over een jaar een merkbaar effect op hun gewicht.
The good news: the calculation is simple if you know your cat's weight. Use the table below as a starting point and adjust based on activity level and condition.
These are guidelines based on the average energy content of dry food (approximately 350–380 kcal per 100 g). Always check the label of your brand: higher calorie density means a smaller portion.
| Cat weight | Kitten (<12 months) | Adult (1–7 yrs) | Senior (7+ yrs) |
|---|---|---|---|
| 2 kg | 45–55 g | 25–35 g | 20–30 g |
| 3 kg | 60–75 g | 35–45 g | 30–40 g |
| 4 kg | 75–95 g | 50–60 g | 40–50 g |
| 5 kg | 90–115 g | 60–75 g | 50–62 g |
| 6 kg | 105–130 g | 70–85 g | 58–72 g |
| 7 kg | — | 80–98 g | 66–82 g |
| 8 kg | — | 90–110 g | 74–90 g |
Neutered cats: After neutering, metabolism drops by 20–30%. Reduce the portion after neutering by 15–20% and monitor weight monthly.
Wet food contains 70–80% moisture and is less calorically concentrated than dry food.
| Cat weight | Wet food only (g/day) | Combined dry + wet food |
|---|---|---|
| 3 kg | 120–150 g | 20 g dry + 80 g wet food |
| 4 kg | 150–190 g | 25 g dry + 100 g wet food |
| 5 kg | 185–230 g | 30 g dry + 120 g wet food |
| 6 kg | 220–270 g | 35 g dry + 145 g wet food |
Handmatig afwegen werkt prima als je er de discipline voor hebt. Maar de meeste eigenaren schenken "op het oog" in, en dat oog is consistent te royaal. Een automatische voerbak programmeert je eenmalig de gewenste portie en geeft altijd exact hetzelfde.
Good portioning takes care of nutrition. A water fountain ensures your cat drinks enough water alongside its dry food.
