A healthy adult cat costs roughly $583–$1,303 a year to keep, plus a one-off $100–$400 in year one for adoption, spay/neuter and starter gear. Of the yearly figure, the supplies we measure from live prices — food, litter — come to about $223.
What we measure vs estimate. The supplies line is a live median from the cat food and litter we track, annualised. Vet, insurance and misc are typical US ranges, not our data. Costs rise with age and any health issue — this is a healthy-adult baseline, not a ceiling.

| Food (5 lb/mo → ×12) | $109 |

Supplies = live median cost per pound × our monthly assumption × 12, re-checked on a rolling cycle. Other lines are typical US ranges. Insurance is optional; excluding it lowers the range.

Vet bills you can’t really shop; food you can. It’s bought by weight, so the number that matters is cost per pound, not the bag price — and store brands with the same core ingredients run well under premium. Buying the biggest bag you’ll finish in about six weeks drops the per-pound cost further. Over a year, that gap is real money on the same bowl of food.
About $583 to $1,303 a year for a healthy adult cat — the recurring cost of food, litter, routine vet care, optional insurance and miscellaneous. Of that, the supplies we price from live listings come to roughly $223 a year; the rest are typical US ranges that vary by where you live. The number climbs with age and any health problem.
More than a typical year: roughly $683 to $1,703. On top of the $583–$1,303 running cost, adoption/spay-neuter + starter gear is typically a $100–$400 one-off. After year one those one-offs go away, so later years cost less.
Food and vet care. Food is the part you control — it's bought by weight, so cost per pound (not the bag price) is the lever, and store brands run roughly half the per-pound price of premium for the same staple. Vet care is the hardest to trim without cutting care, and a single unexpected illness or injury can add hundreds to thousands in a year, which is what pet insurance is meant to smooth.
