How Much Does Cat Food Cost per Month? About $8 Dry, $82 Canned, and the Calorie Math Behind the Gap
Ask what cat food costs per month and the honest answer runs from about $8 to more than $90 for the same 10-pound cat. The gap is not brand snobbery. It comes from how many calories a cat needs, what each calorie costs in a bag compared with a can, and how much water you pay to ship. This guide converts published feeding guides and October 2026 shelf prices into a monthly figure for dry food, canned food and a mix of the two, then places those numbers next to what surveys say cat owners actually spend.
Start with calories, not cups
Every feeding bill is a calorie bill. Tufts University's Cummings Veterinary Medical Center puts an average-activity 10-pound adult cat at about 290 kcal a day, and the Cornell Feline Health Center puts an 8-pound cat at roughly 200 to 250. Those are starting points rather than prescriptions; Tufts itself says a cat's real intake and body condition are a better guide than any table. For the arithmetic below, 290 kcal a day for a 10-pound cat is the working number, and the product labels land close to it.
Dry food: roughly $8 a month
Purina Cat Chow Complete lists 411 kcal per cup and about 3,688 kcal per kilogram. Its feeding guide gives a 10 to 14 pound cat 2/3 to 3/4 cup a day, which is 274 to 308 kcal. A 16-pound bag was listed at $24.98 at Walmart, about $1.56 a pound. Sixteen pounds is 7.26 kg, or roughly 26,800 kcal, which feeds a 290-kcal cat for about 92 days. That works out to about 27 cents a day, or $8 a month. Premium dry formulas cost more per pound, and I did not price them here, so treat $8 as the floor rather than the typical bill.
Canned food: roughly $80 a month
Wet food is priced by the can, and the cans are small. Fancy Feast Classic Pate lists about 88 to 91 kcal per 3-ounce can depending on flavor, and its feeding guide says one can per 3.5 pounds of body weight daily. For a 10-pound cat that is about 2.9 cans, or roughly 260 kcal. A 24-can case was listed at $22.86 to $23.04 at Walmart, about 95 cents a can. At 2.9 cans a day, the cost is about $2.75 a day, or $82 a month. Feeding all 290 kcal from cans would push that past $90.
Why a cheap can can still cost more
Friskies Classic Pate in 5.5-ounce cans was listed at $19.99 to $20.16 for 24 at Chewy and Walmart, about 83 cents a can or 15 cents an ounce, against roughly 32 cents an ounce for Fancy Feast. The ounce price flatters the bigger can, because canned food is mostly water and labels vary in calories per can. The comparison that matters is cost per 100 kcal: divide the can price by the kcal on its label, then multiply by the 290 you need. Do that before trusting any per-ounce sticker.
A half-and-half diet costs about $50
Many owners split the day, a little canned food for moisture and flavor with dry food for the rest. Feed half the calories each way, about 145 kcal from each, and the figures above give roughly $4 a month for the dry half and $46 for the canned half, so around $50 in all. Canned food is the lever. Every can you swap for dry saves about 85 cents a day at these prices, so a cat that gets one can a day plus dry food for the remaining calories costs about $34 a month.
What owners really spend
According to the American Pet Products Association's 2025 survey, as reported by trade press, cat owners spent an average of $337.53 on food that year, or about $28 a month. That sits between the dry-only and canned-only figures, which fits a mixed diet bought at ordinary stores. Pet food prices themselves are fairly steady. The federal consumer price index for pet food and treats rose 1.6% year over year in August 2026, up from 1.3% the month before, though it remains about 25% above January 2020.
Where food fits in the rest of the budget
Food is only part of the year. Our full yearly cost of a cat adds the vet, litter and supplies, and the cat versus dog comparison shows where cats run cheaper. Litter has its own line in the cat litter cost guide. Prescription diets, which can cost far more than the figures here, are covered in the insurance guide to prescription food.
A quick way to price your own cat
Take the calories on your cat's current food label, find the kcal per cup or per can, and divide your cat's daily need by it. Multiply the cups or cans by the price per unit and by 30. Prices were taken from retailer listings in October 2026 and change often, so treat each figure as an example rather than a quote.
This guide covers costs only. It is not veterinary advice; ask a veterinarian how much and what to feed your cat, especially if it is overweight, underweight or has a medical condition.
