Longevity
Life expectancy
The Siamese is one of the cat breeds that can live a long time when it benefits from good lifestyle hygiene, regular preventive monitoring and a suitable diet. A longevity of 15 to 21 years is possible, with many individuals remaining active and expressive until late in their life.
Build
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 rustic cats lifestyle mistakes or an environment poorly suited to its need for activity and contact.
Watch points
What to watch 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
Cold and heat tolerance
With its short coat and the absence of a marked undercoat, the Siamese is more comfortable in a temperate indoor environment than in a cold climate. It appreciates warm places and comfortable bedding, while strong heat requires shade, fresh water and good ventilation.
Weight
Tendency to gain weight
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.
Daily life
Good habits to keep it 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 that is transparent about health history.
Vaccination
Siamese vaccines: vaccination schedule
Which vaccines for a Siamese? Like all cats, the Siamese receives essential vaccines from 8 weeks old: Typhus (panleukopenia) and Coryza. The kitten primary vaccination for Siamese is given in several injections 4 weeks apart, followed by a first booster at 1 year, even if it lives in an apartment. Depending on its lifestyle (outdoor access, multi-cat household, shows, travel), your veterinarian may complete the protocol with vaccines against Feline leukemia (FeLV), Rabies and Chlamydiosis.
| Vaccine | Primary series | First booster | Then | Who for? |
|---|---|---|---|---|
Typhus (panleukopenia)Core Feline panleukopenia (cat parvovirus) | 8 weeks · 12 weeks · 3 months | 1 year | every year | All pets |
CoryzaCore Feline herpesvirus and calicivirus | 8 weeks · 12 weeks · 3 months | 1 year | every year | All pets |
Feline leukemia (FeLV)Lifestyle-based Feline leukemia virus | 8 weeks · 12 weeks | 1 year | every year | Outdoor cats, cats living in a group or in a cattery |
RabiesLifestyle-based Rabies | 12 weeks | 1 year | every year | Mandatory for travel abroad, cat shows and most boarding kennels |
ChlamydiosisLifestyle-based Chlamydia felis (contagious conjunctivitis) | 8 weeks · 12 weeks | 1 year | every year | Cats living in groups, catteries, show cats |
Adult Siamese vaccine boosters are annual for cat flu and leukemia if it goes outdoors; for panleukopenia, a booster every three years is often sufficient after the first booster. Your veterinarian will adjust the schedule to your cat’s lifestyle.
