What is the average lifespan if a Siamese cat?

my Siamese cat is 16 years old...was wondering if anyone else's Siamese cat has lived that long?

AnswerMy Siamese is almost eighteen. The average lifespan for Siamese cats is fifteen to twenty years, but some are known to live longer than that. Siamese cats are known for having longer lifespans than most other housecats.
