Felynn are depicted as cat girls with long hair tied in a ponytail, with such features as large feline ears, a large bushy tail, arms and legs covered in fur beginning just above the elbows and knees, and large paws instead of hands and feet. They are also depicted with exaggeratedly curvaceous bodies, having comically large breasts and muscular thighs. They wear extremely little clothing, having only small strips of cloth that covers their crotch and partially covers their breasts, and nothing more.
They are a clan that have a unique style of martial arts, and their cat ears have garnered them many fans throughout the netherworlds. According to Afternoon of Darkness, Felynn get along with the Succubus clan.

In Disgaea: Hour of Darkness, Kit Cats first appear in Chapter 5, alongside the Succubi that Maderas hired. Among the monster classes, they have one of the highest natural counter rates in the game. Because they make their first appearance in a stage protected by the Invulnerability Geo Symbol, with a little patience, it is possible to merge and capture a Kit Cat as high as above Level 100.
