How Much Does Cat Food Cost Per Day Wet Versus Dry

Cat food costs about $0.70 to $1.80 per day for an adult cat on dry food, $1.50 to $3.50 per day on wet food, and $1.00 to $2.50 per day on a mix of wet and dry food in the US in 2026. A mix is the most common choice, and it costs about $30 to $75 per month. In the UK, cat food costs about £0.60 to £1.50 per day on dry food, £1.20 to £3.00 per day on wet food, and £0.90 to £2.00 per day on a mix.

Cat food cost per day is the number that matters for budgeting, because it turns a bag or case price into a daily cost you can compare. A $30 bag of dry food that lasts 40 days costs $0.75 a day. A case of wet food that costs $25 and lasts 10 days costs $2.50 a day. The wet food costs more than three times as much per day, even though the case price looks lower. This guide gives you cost per day for wet food, dry food and a mix, by cat size and life stage, with a worked example, a UK section, and a comparison by cost per calorie. Every price is a range, because brand, quality and where you buy change the price a lot.

Cat food cost per day: wet versus dry

Wet food costs more per calorie than dry food, because it is mostly water. A typical wet food has about 80 to 100 calories per 100 grams. A typical dry food has about 350 to 400 calories per 100 grams. That means a cat needs about 4 times as much wet food by weight as dry food for the same calories. That is why wet food alone is so much more expensive per day, even when a single can looks cheap.

How much does a cat eat per day

An average adult cat of about 4 to 5 kg needs about 200 to 300 calories a day. That is about 50 to 80 grams of dry food, or one to two small cans of wet food, or a mix of both. A small cat of about 3 kg needs about 180 to 220 calories a day. A large cat of about 6 to 7 kg needs about 280 to 350 calories a day. A very active cat or an outdoor cat needs more. An older cat or a less active cat needs less. Weigh the food with kitchen scales for a week, because scoops are not accurate and most owners overfeed by 10 to 20 percent without realising it. If your cat is gaining weight, ask your vet how many calories it needs, and cut the food, not the quality.

Worked example: a 4.5 kg cat on a mix

Take a healthy adult cat that weighs 4.5 kg, with normal activity. It needs about 250 calories a day. Suppose you feed half the calories as dry food and half as wet food. The dry food has 3,800 calories per kg and costs $30 for a 3 kg bag, which is $10 per kg. Half the calories is 125 calories, which is about 33 grams of dry food, costing about $0.33 a day. The wet food has 90 calories per 100 grams and costs $1.20 per 85 gram can, which is about 77 calories per can. Half the calories is 125 calories, which is about 1.62 cans, costing about $1.95 a day. The total is about $2.28 a day, or about $68 a month. If you feed dry food alone, the same 250 calories costs about $0.66 a day. If you feed wet food alone, the same 250 calories costs about $3.90 a day. The mix costs more than dry food alone, but much less than wet food alone, and many cats eat a mix more happily than dry food alone.

How much does cat food cost per day by life stage

Kittens need more calories per kg than adult cats, because they are growing. A kitten eats about 2 times the adult amount per kg in the first months, then less as it grows. Kitten food costs about $1.00 to $2.50 a day on a mix, $0.80 to $1.50 a day on dry food alone, and $2.00 to $4.00 a day on wet food alone. Adult cats need the amounts in the table above. Senior cats often need fewer calories, because they are less active, but they may need a more expensive senior or prescription food. A senior cat on prescription food can cost $2.50 to $5.00 a day, even though it eats less. Ask your vet which life stage food your cat needs, and do not feed kitten food to an adult cat, or adult food to a kitten, without vet advice.

How much does cat food cost per day in the UK

In the UK in 2026, dry cat food costs about £0.60 to £1.50 per day for an adult cat. Wet cat food costs about £1.20 to £3.00 per day. A mix of wet and dry costs about £0.90 to £2.00 per day. Premium and prescription food costs about £1.80 to £3.50 per day. Supermarket own brand food is cheapest, often £0.60 to £1.20 a day on a mix. Premium and vet recommended brands cost more, often £1.50 to £2.50 a day on a mix. Buy in larger packs when the price per kg is lower, and check the price per day, not just the pack price.

How to compare cat food fairly

Compare food by cost per day and by cost per 1,000 calories, not by bag or can price. To work out cost per 1,000 calories, take the price of the pack, divide it by the total calories in the pack, then multiply by 1,000. A bag that costs $30, weighs 3 kg, and has 3,800 calories per kg, has 11,400 calories in total. That is $2.63 per 1,000 calories. A cheaper bag that costs $20, weighs 2 kg, and has 3,200 calories per kg, has 6,400 calories in total. That is $3.13 per 1,000 calories. The cheaper bag is more expensive per calorie, and it will run out sooner. Use cost per 1,000 calories when you compare brands, and use cost per day when you budget.

How to reduce cat food cost without cutting quality

Buy larger bags and cases when the price per kg is lower, and store the food well so it stays fresh. Weigh the food, because overfeeding by 20 percent adds 20 percent to your food bill and harms your cat. Cut treats to 10 percent of daily calories or less, because treats are expensive per calorie and they add weight. Compare cost per 1,000 calories before you switch brands, and switch slowly over a week so your cat's stomach can adjust. Ask your vet if a mid priced food is enough for your cat, because many cats do well on a good mid priced food and do not need the most expensive brand. Do not buy food in bulk if your cat will not eat it, and do not buy a food that upsets your cat's stomach just because it is cheap. If your cat is a picky eater, buy small packs first, then buy larger packs once you know it will eat the food.

Frequently asked questions

Is wet food better than dry food for cats?

Both can be good if they are complete and balanced. Wet food has more water, which helps hydration and kidney health, and many cats prefer the taste. Dry food is cheaper per calorie, better for teeth, and easier to store. A mix of both is a good choice for many cats.

How much wet food should a cat eat per day?

An average adult cat needs about 200 to 300 calories a day. One small 85 gram can has about 70 to 90 calories, so a cat on wet food alone needs about 3 to 4 cans a day. Most owners feed 1 to 2 cans plus dry food, which is a mix.

How much does it cost to feed a cat per month?

A cat costs about $21 to $54 a month on dry food, $45 to $105 a month on wet food, and $30 to $75 a month on a mix. Read our cat cost per month guide for the full monthly total, including litter, vet care and insurance.

Can I feed my cat cheaper food to save money?

You can, but compare cost per day and cost per 1,000 calories first. A cheap food that your cat needs more of, or will not eat, can cost more per day than a mid priced food. Ask your vet if a cheaper food is complete and balanced for your cat's age and health.

How long does a bag of cat food last?

A 3 kg bag of dry cat food lasts about 40 to 60 days for one cat eating 50 to 80 grams a day. A case of 24 cans lasts about 6 to 12 days for one cat eating 2 to 4 cans a day. Weigh the food to know the real number for your cat.

Sources and how we priced this

Prices in this guide are ranges, not single facts, because published sources disagree. We used the American Pet Products Association 2025 and 2026 industry figures, Rover 2026 cost of dog ownership reports, the PDSA PAW Report and PDSA cost guides for the UK, the American Animal Hospital Association and the National Research Council feeding guidance, and published insurer and vet price lists in the US and the UK. All prices were checked in Nov 2026 and are shown in US dollars unless a UK section says pounds. Where a source gave one number, we widened it into a range to reflect size, breed and location.
