Kitty Katswell is the co-protagonist of T.U.F.F. Puppy. She is T.U.F.F.'s #1 agent. Kitty 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. Kitty is an agent at the Turbo Undercover Fighting Force, and is regarded as one of its greatest agents. Her claws are registered lethal weapons, and she is proficient at using many weapons, gadgets, and disguises. She is also shown to be very athletic, being able to do a lot of physically challenging actions that come in handy during her missions. Despite this, she does have a few weaknesses, such as her shaky relationship with her mother and sister, or her schoolgirl-like love for Eric, the water delivery guy which can distract her (even in combat). Kitty was even trained to be skilled in combat (martial arts), languages (120 dialects) and firearm usage. Kitty is a tall, athletic and tan-furred anthropomorphic cat who stands at 5 foot 6", excluding hair and ears (as shown in The Doomies), with large lime-green eyes, a long tail, retractable claws and whiskers, though the whiskers have only been seen in Doom-Mates. Her black hair is mid-length, wavy, with bangs, and fashioned into a 1960s styled Flip hairstyle. Kitty's attire consists of a two-piece, popped-collared dark teal suit and belt. Additionally, her headband, turtleneck top, gloves and high-heeled boots are white. In Watch Dog, as a secretary, she wears glasses, and has a hair bun. Sometimes, the irises in Kitty's eyes turn bright red whenever she would get very angry. Younger versions of Kitty have been shown and vary from episode to episode, but most consistently have her with freckles and wearing braces. Her hairstyles take many features from Trixie Tang and Tootie from The Fairly OddParents, notably the long straight hair with headband or pigtails. Kitty was also turned into a baby by the Young Gun and had darker hair on her belly, and later, an elderly woman with a walker and tiny purple glasses.
