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 9 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, so this one's popularity is hard to gauge; what is breed-specific here is the survival data. 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.
