A Siamese — 8–12 lb for males and 5–8 lb for females — costs a typical owner in Texas about $1,466 a year, or $968 to $1,829 depending on food, litter and insurance. That is right at the average for the 15 cat breeds we track.
Vet and preventive care is the largest line at 39%: 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 8.3 lb this one sits in the middle band. Food is only 16% (265 kcal a day).
The CFA publishes ranks only for its top ten breeds, and no registry we use counts this one, so how common it is cannot be said from data we can check. Its 11.69-year life expectancy from the UK survival study is close to the crossbred cat's 11.9. The breed library quotes 8–12 years. At 8.3 lb it is an average-sized cat: 265 kcal a day, middle flea-prevention band.
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: $2,370. 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 11.69-year median lifespan the total is $18,376; the final 2 years run about $1,664 each once senior exams and bloodwork are added.
