At first glance, they appear to be a group of innocent-looking kittens one can't help but adore. Underneath, however, they are lethal, merciless, efficient fighters. However, once they see a ball of yarn or a dish of cat food - even in battle - they instantly revert to adorable balls of fur. They are also world famous as rock stars and stage actors. While performing on stage, they show no signs of their true nature. Yang was once their biggest fan (as seen in "My Stupid Sword"), but ever since he was betrayed by the Kitties, they have become bitter rivals and have lost his favor. They are also shown to be very obstinate, constantly trying to break into the Woo Foo Armory without giving up.
In the episode "The Gig is Up", the Kitties sought to get back at their foes by stealing Laladin's Amp - a magical Woo Foo amplifier that enhances music and hypnotizes those who hear it. They used the Amp to hypnotize the audience at a Battle of the Bands, bending everyone in the audience to their will. The Kitties were close to being successful, buy Master Yo fired a blast from his guitar, splitting the Amp in two.
In the episode "Out on a Pledge", the Kitties moved into a house across the street from the dojo, disguised as a group of fraternity boys. Yang, who felt he was in need of some male bonding at the time, hung out with them, unaware then of their disguises. Eventually, they were exposed by Yin, and Yang was shocked after learning he had been hanging out with a sorority. When the Kitties saw the pajamas Master Yo was wearing, they found it so funny that they let go of the weapons they had stolen, leaving them vulnerable. Once Yin and Yang had beaten the Kitties, they were evicted from the house and sent on their way.
In the episode "Cat Smash Fever", the CPK broke up after Yin and Yang gossiped about them on the Internet. Afterwards, each one quickly formed a new group of her own. The CPK later got back together after seeing a video tribute dedicated to them.
