How often do Siamese Cats talk?

Depends on their personality. You should ask the shelter or breeder what "lynx" is like. Maybe they will be able to tell you about that kitten how often it meows. I have a barn cat who looks like be must have some siamese in him, and he doesn't meow much. Only when he wants me to feed him or when he wants to bring me somewhere ( usually to the food or his water bowl) lol.
