Cheetah Unknown is a stray cat living in Appaloosa Plains.
Cheetah was thrown out by her owners. She had started to behave badly because she was upset that one of the members of the family had died. Cheetah gained the aggressive trait upon leaving the household, as she was from then on disgusted about how she had been treated.
She will hiss and attack any sims that she sees, although she is relatively friendly about socializing with other cats. She has a high hunting skill, and as a result always has something to eat as she wanders through Appaloosa Plains, watching Sims from alleyways.
She is the mate of Tiger Bell.
