JetCat was a comic book series created by Jay Stephens (of Tutenstein and The Secret Saturdays fame). The series is about a young girl named Melanie Ilk who becomes a feline superhero named JetCat in which she flies like a jet and fights like a cat. The comic book later spun off into four animated shorts that aired in the third and final season of Nickelodeon's KaBlam!. The character by the name of Tutenstein was later used for Stephen's cartoon series of the same name that lasted from 2003 through 2008. The shorts were managed by PorchLight Entertainment. It was nominated to Annie Award.
