How much does premium food for an adult cat cost per month?

An adult cat's budget depends above all on the share of wet food in the ration, because wet food costs more per calorie than kibble. A 4 kg (9 lb) cat needs only about 200 to 250 kcal a day, but an all-wet or mixed ration lifts the monthly cost markedly compared with all-dry feeding. In depth ### Wet food is the real variable in the feline budget For a cat, the line that moves the budget is not body size but food format: wet food delivers few calories per gram, so its cost per calorie exceeds that of dry. A 4 kg cat covers a maintenance need of about 200 to 250 kcal a day; serving it premium pouches rather than dense kibble changes the total markedly, at comparable nutritional quality. The market illustrates this tension. In France, wet food weighed 320,500 tonnes against 847,500 tonnes of dry in 2024, and its growth is driven by premiumisation (FACCO, 2024; FACCO, 2025). A little-known fact: wet food often contains 75 to 80 per cent water, so part of the price per kilo pays for water, which makes cost per calorie far more meaningful than price per kilo for a cat budget. ### Costing the feline diet on an energy basis The reliable method relates price to the caloric need, not to product weight. To compare dry and wet, one works out the cost of the kcal covered per day in each format, then adds them according to each share. This energy basis, recommended by WSAVA, neutralises the misleading effect of the water in wet food (WSAVA, 2021). Comparison table | Format | Caloric supply | Effect on the cat budget | |---|---|---| | Dense kibble | high per gram | low cost per calorie | | Premium pouch | low per gram (75 to 80 per cent water) | high cost per calorie | | Mixed ration | intermediate | depends on the wet share | | Treats (under 10 per cent) | counted in the total | marginal if capped |
