Kitty Katswell is T.U.F.F.'s #1 agent. She is also an expert in combat, weapons, and detective work. She is Dudley's partner, assigned to train him as a T.U.F.F. agent, but often finds herself and her skills foiled by Dudley's antics. Her claws are registered lethal weapons, and she is proficient at using many weapons, gadgets, and disguises. She is a young, attractive but agile and strong anthromorphic cat. Her cat instincts tend to get the best of her, like chasing mice.
