A Devon Rex — 5–8 lb, No. 5 in the CFA's 2025 registration ranking — costs a typical owner in Texas about $1,414 a year, or $927 to $1,760 depending on food, litter and insurance. That is 6% below the $1,507 average across the 1 cat breeds we track.
Vet and preventive care is the largest line at 40%: 1 exam, core vaccines, dental every 3 yrs, 12 months of flea/heartworm prevention. Monthly flea and heartworm prevention makes up most of it — cats are dosed by weight band, and at 6.5 lb this one sits in the middle band. Food is only 13% (205 kcal a day).
The CFA ranks it No. 5 of its ten most-registered breeds; the running costs below come from size and coat, not from the kitten price. No breed-level survival study covers the breed, so the 11.54-year figure is the US life expectancy for purebred cats; the breed library quotes 9–13 years. A small cat of this size needs only about 205 kcal a day and sits in the cheapest flea-prevention band, which is why the yearly total is near the floor for cats.
A shorthair is the cheapest coat to keep: a weekly brush, no trimming, no salon. Shedding still happens — the de-shedding tool in the gear list handles it.
First-year total: $2,318. Beyond the running costs that includes spay or neuter ($299 at Texas prices), the kitten vaccine series with its extra visits, and $294 of gear — litter box, scoop, carrier, bowls, bed, scratcher, cat tree and grooming tools.
Over a 11.54-year median lifespan the total is $17,556; the final 2 years run about $1,631 each once senior exams and bloodwork are added.
