Mr. Whiskers is a silly, sloppy, smelly, gross, hyperactive, and overall annoying pest. Mr. Whiskers is actually intelligent with a fairly large vocabulary, which is exhibited at special moments. He is also very loving and caring, but he can be clumsy and clueless at times although he is arrogant and naughty. He can be selfish, short-tempered and cranky. Like all toons, Whiskers fears the dip more than anything else.
- Whiskers shares a few things in common with Buster Bunny: Both are rabbits that were previously voiced by Charlie Adler.
