Longevity
Life expectancy
The Siamese is among the cat breeds that can live a long time when it benefits from good hygiene, regular preventive monitoring, and a suitable diet. A lifespan of 15 to 21 years is possible, with many individuals remaining active and expressive until late in their life.
Constitution
Is this a robust breed?
Its robustness is average. The Siamese is generally solid, but it requires particular attention to certain hereditary predispositions and tolerates less well than more hardy cats lifestyle mistakes or an environment poorly suited to its need for activity and contact.
Things to watch for
What to look out for
Vigilance must above all focus on hereditary conditions and on the impact of stress or boredom in this sensitive cat that is very attached to its habits. Serious breeding, regular check-ups and careful observation of changes in behavior are essential.
Amyloidosis: Predisposition to protein deposits that can notably affect the kidneys and liver and progressively impair their function.
Aortic stenosis: Congenital heart disease corresponding to a narrowing that disrupts the ejection of blood into the aorta.
Climate
Tolerance to cold and heat
With its short coat and the absence of a pronounced undercoat, the Siamese is more comfortable indoors in a temperate environment than in a cold climate. It appreciates warm places and comfortable bedding, while intense heat requires shade, fresh water and good ventilation.
Weight
Prone to weight gain
The Siamese is an active cat, but its weight must remain monitored to preserve its slender silhouette and mobility. A measured ration, quality food and daily play help prevent weight gain without frustrating a cat that is very demanding of interaction.
Everyday care
Good habits to keep your pet healthy
- Schedule an annual veterinary check-up, then more frequent ones with age.
- Monitor any decrease in appetite, unusual fatigue, or change in thirst.
- Maintain a stimulating environment to limit stress and boredom.
- Choose a breeder who is transparent about health history.
Vaccination
Siamese vaccinations: schedule
Which vaccines does a Siamese need? Like all cats, Siameses should receive their core vaccines from 8 weeks of age: Typhus (panleukopenia) and Coryza. Kittens receive their initial Siamese vaccinations in several shots spaced 4 weeks apart, followed by a first booster at 1 year, even if they live indoors. Depending on their lifestyle (outdoor access, living with other cats, shows, travel), your veterinarian may add vaccines against Feline leukemia (FeLV), Rabies and Chlamydiosis.
| Vaccine | Primary vaccination | First booster | Then | For whom? |
|---|---|---|---|---|
Typhus (panleukopenia)Core Feline panleukopenia (cat parvovirus) | 8 weeks · 12 weeks · 3 months | 1 year | every year | All animals |
CoryzaCore Feline herpesvirus and calicivirus | 8 weeks · 12 weeks · 3 months | 1 year | every year | All animals |
Feline leukemia (FeLV)Depending on lifestyle Feline leukemia virus | 8 weeks · 12 weeks | 1 year | every year | Outdoor cats, cats living in a group or in a cattery |
RabiesDepending on lifestyle Rabies | 12 weeks | 1 year | every year | Mandatory for travel abroad, cat shows and most boarding kennels |
ChlamydiosisDepending on lifestyle Chlamydia felis (contagious conjunctivitis) | 8 weeks · 12 weeks | 1 year | every year | Cats living in groups, catteries, show cats |
Adult Siamese booster shots are given annually for feline herpesvirus and feline leukemia if your cat goes outdoors. For feline panleukopenia, a booster every three years is often enough after the first booster. Your veterinarian will tailor the schedule to your cat's lifestyle.

Choosing well
Adopting a healthy Siamese
Veterinary follow-up including an annual clinical examination, heart monitoring, kidney function checks according to age, and verification of oral and dental status is relevant. In case of family history, targeted screening with the veterinarian may be recommended.
