Slug and Bootlick are the tertiary antagonists in An American Tail: The Mystery Of The Night Monster. They are two of Twitch's cat gang called the Outlaw Cats and Twitch's primary followers. Both Slug and Bootlick are dimwitted. At the near end of the movie, they were chased away by the Dog Council. Later it is revealed that the Outlaw Cats (probably including Slug, Bootlick, and even Twitch) were last seen fleeing up East Avenue, and were not seen again.
Bootlick was voiced by Joe Lala and Slug was voiced by Jeff Bennett.
- Along with Twitch, Slug and Bootlick could be two of the followers of Warren T. in the first movie, which explains why they lived in the sewers with the other cats.
