Ball-tailed cat

The ball-tailed cat originates in the corpus of North American "fearsome critters" — tall-tale animals created and circulated by woodsmen and frontier communities around the turn of the 20th century. These stories blended recognizable natural forms (notably the mountain lion) with grotesque or humorous exaggerations; the ball-tailed cat is presented as a fanciful catlike predator whose extraordinary tail-ball supplies the memorable twist. The tradition is occupational and playful, producing pseudo-scientific labels (e.g., the jocular Felis caudaglobosa) and named variants rather than a mythic cosmogony.

Overall form resembles a large felid comparable to a mountain lion: muscular, catlike body adapted to forested or mountainous terrain. Its distinguishing anatomical feature is an exceedingly long tail that terminates in a solid, bulbous mass or "ball." In at least one variant called the "Sliver Cat," the tail-ball is described as having two faces: one smooth side used to knock wayfarers unconscious and a spiked side used to pierce and grapple victims. Popular accounts at times present the scientific-style jocular binomial Felis caudaglobosa to underscore the hybrid of naturalistic and fanciful description.

Primary behavior reported is use of the ball-ended tail as a weapon: striking prey or human passersby with force. Descriptions of variants attribute different effects to the tail-ball — the smooth face can render a person unconscious by concussive blows, while a spiked face (in the Sliver Cat variant) can pierce and grapple victims. Implicitly, it stalks or occupies the same environments as mountain lions (woods, trails) and attacks or incapacitates humans or animals encountered on the path. Accounts are presented as tall-tale narrative devices rather than systematic supernatural power-lists.
