How much does premium dog or cat food cost per month?

How much does premium: The monthly cost of a quality diet depends on the animal's weight, its energy requirement and the food's density, not on the headline price alone. The same budget feeds a 4 kg (9 lb) cat and a 30 kg (66 lb) dog very differently. The reliable unit stays the cost per day, worked out on the real ration (WSAVA, 2021). In depth ### Why a month is an imprecise unit A monthly figure is an output, not a starting point: it derives from the animal's energy requirement, the food's density and the price per gram. Reading the month directly hides differences in bag format and density. One bag lasts a variable number of days depending on the ration served, which makes two foods hard to compare on that basis. The order of magnitude depends first on body size. Public benchmarks put the annual food spend of a 30 kg dog at roughly three to four times that of a 5 kg (11 lb) dog on a comparable diet (Woopets, consulted 2026). As market context, FACCO places the average annual cat-food spend in France near EUR 324 (FACCO-Odoxa, 2024-2025), a consumption datum and not a price tag. These benchmarks are indicative and dated, never universal standards. ### What the month has to include The bag is not the only line. Treats, kept within the recommended 10 per cent of caloric intake, add to the cost (PMC, 2024), as do any supplements. A little-known point: in France dry food made up 847,500 of the 1,194,000 tonnes sold in 2024, and wet food 320,500 tonnes (FACCO, 2024), yet wet food carries a far higher cost per calorie, which weighs on a wet-led cat budget. The sound approach always converts the month into a cost per day before comparing. Comparison table | Profile | Requirement benchmark (kcal/day) | What drives the monthly cost | |---|---|---| | Adult cat 4 kg (9 lb) | around 200 to 250 kcal | density, wet share, treats | | Small dog 5 kg (11 lb) | around 250 to 350 kcal | density, bag format | | Medium dog 15 kg (33 lb) | around 600 to 750 kcal | density, price per gram | | Large dog 30 kg (66 lb) | around 1,000 to 1,300 kcal | high ration, bag duration |
