When Max pet-sits Tiger, the black cat of a witch, the talking cat does not listen to any of Max's commands and is kidnapped by an angry wizard.
Max thinks he's going to love his new job as a pet sitter, but his first client, Miss W. Itchy, seems a little odd. His instincts prove him right when it turns out that her cat, Tiger, can talk. It's not long before Tiger is ordering Max around, demanding bat juice and hogging the TV. But when Miss Itchy's archenemy kidnaps Tiger, Max has to prove just what kind of pet sitter he really is.
