One of the last animated shows produced at Studio B Productions before it was renamed in 2011.
In the "Look What My Sister Dragged In" pilot, Coop and Kat were voiced by Ian James Corlett and Louis Chirillo. They were later voiced by Erin Mathews (Coop) and Kathleen Barr (Kat) in the full series. Trevor Devall and Barr are the only voice actors to reprised their roles from the pilot.
Rob Boutilier began creating the show back in 2003. He was inspired by people's reaction to his hairless cat as they thought it looked like an alien. Boutilier then came up with the idea if the cat was truly evil.
