A mature Japanese hairy cat with an Asian-looking black marking on its chest and black tufts of hair behind its ears is called a Squirrelfish. Squirrelfishes are commonly kept as pets and show great affection for their owners. The male is completely hairless (no hair is present on the female) and lives up to about twelve years. The hairless male is occasionally seen lurking under a piece of lettuce or cabbage leaves, watching unsuspecting victims as they try to get around him..
