Totally Persians specializes in teacup size kittens which range in weight from 7-9 pounds when full  grown. There is more to these adorable kittens than their soft fur, big round eyes and mitten-like paws. Persians are an exquisite breed that are typically affectionate, quiet, and content to lay around. Considered to be one of the oldest breeds, Persian cats can be traced all the way back to the 1600's to Mesopotamia, later called Persia.
