Addictional informatio n (Wiki): Siamese are affectionate and intelligent cats, renowned for their social nature. They enjoy being with people and are sometimes described as "extroverts". As there are extrovert siamese, there also are very sensitive and nervous temperaments, which are not easily adapted to the changes of environment or to strangers. They are extremely vocal, with a loud, low-pitched voice – known as "Meezer", from which they get one of their nicknames – that has been compared to the cries of a human baby, and persistent in demanding attention. They also have a great need for human companionship. Often they bond strongly to a single person. These cats are typically active and playful, even as adults.

The social orientation of Siamese cats may be related to their lessened ability to live independent of humans. Siamese coat colouration is appealing to humans, but is ineffective for camouflage purposes. They are less active at night than most cats, possibly because their blue eyes lack a tapetum lucidum, a structure which amplifies dim light in the eyes of other cats. Like blue-eyed white cats, they may also have reduced hearing ability, though most are not deaf; indeed, Siamese are known for being an exception to the rule of thumb that white cats with blue eyes are deaf. Regardless, being dependent on humans may have been a survival trait for ancestors of the Siamese.
