Stinky is the purple cat of Roger Klotz in the Doug franchise. Although it is always assumed that Stinky is male, it is revealed in the episode, Roger's Fat Cat, that Stinky is female and pregnant. Like all the other animals, Stinky behaves very much like a human, and can walk on two legs just like the other pets and animals in the show.
Stinky, first and foremost, loves her owner Roger Klotz. Briefly Judy Funnie develops a liking for Stinky in the episode Roger's Fat Cat. Stinky despises Doug's dog Porkchop and the two usually get into fights.
