Siamese

Siamese can do well with children who already know how to be calm and gentle. Expect an average-sized cat that is high-energy, barely sheds and needs very little grooming. It is a committed lap animal, so expect company whether or not you asked for it.
The numbers
| Typical lifespan | 11–15 years |
|---|---|
| Average adult weight | 5.2 kg (about 11.5 lb) |
A second number, from veterinary records. A 2024 study of UK veterinary records put life expectancy for Siamese at 11.69 years (95% confidence interval 10.56–12.82). That is measured from birth across every cat of this breed in the data, which makes it a different measure from the range above — and it lands in much the same place. UK cats of every kind average 11.74 years on that same measure.
Based on 88 recorded deaths.
The oldest Siamese in that data reached 21.48 years.

What Siamese are actually like
Day to day. High-energy — this is a cat that needs height to climb, things to hunt and someone to play with. A bored one of these gets into everything, and that is not naughtiness, it is boredom.
The coat, honestly. This breed barely sheds and needs very little grooming. A brush a few times a week and the occasional tidy-up keeps it in good order.
Company and noise. This one is a committed lap animal and very talkative. Expect it on your lap, your keyboard and your chest at six in the morning — a cat bred for closeness does not negotiate. And it will talk to you constantly, expecting an answer.
Get one if…
- Someone will actually play with it every day, and it can climb high
- You would rather brush and pay a groomer than vacuum every day
- You want a cat whose coat looks after itself
- You want an animal that actually sits on you, not just near you
- You would enjoy a pet that genuinely talks back
Think again if…
- Nobody has ten minutes twice a day to play with it properly
- Anyone in the house needs quiet to sleep, work or study
- You want a pet that entertains itself while you get on with things
What it costs to keep one
Rough running cost: $$ (middle of the pack) — because there is no single expensive thing about it — just the normal food, vet and insurance costs every cat brings.
Those are relative bands, not live prices. For real numbers across every pet we cover, see the pet cost study and the cost calculator.

Rescues do have Siamese and Siamese crosses, usually adults whose size, coat and temperament you can see rather than guess at.

❓ Common questions about Siamese
Is a Siamese good with kids?
They can be, with children who are already calm and gentle around animals. Siamese suit families with school-age kids better than families with toddlers.
Do Siamese shed a lot?
Very little. The trade is grooming: this coat needs regular brushing and professional trims, or it mats.
Can a Siamese be left alone during the day?
Less happily than most cats. This breed was bred for close human company and tends to be vocal and unsettled when the house is empty all day — two cats together suits it far better than one alone.
Is a Siamese a good first cat?
It can be, for a household with older children and realistic expectations about how much this breed wants to be handled.
Should I get a Siamese?
Siamese suit a home that moves a lot, is happy to be climbed on, and is not fussy about coat care. Meet the cat itself before deciding.
