Jet Jet is an alley cat. He appears to be Dongwa's family rival, although he is sometimes usually just portrayed as a bully, he was the only one who helped Sagwa and her siblings with the mice showing he has a softer side and including being nice to Sagwa and showing where Dongwa was. (this may have included a deleted scene where he showed his villainous side though as he isn't present in the end). He is friends with the other Alley Cats, including Wing Wing, Hun Hun, and Lik Lik. He is a gray Tabby, with light gray fur and black markings, including his signature thick "eyebrows".
He is voiced by Erik von Detten.
