my grandma's cat is wild like that, it was a stray. shes still really small, and has rougher fur than normal, and has little ear tuffs, the vet thinks she might be part bengal. but she goes on the rafters in the family room, trying to get into the skylights. then she either falls, or causes a little dust flurry. she used to knock my grandpa's toy truck collection off the rafters, but my grandma took them all down. shes a bad kitty, but shes so CUTE! and shes nicer now, sorta. well, not really. at least she doesnt attack every bare ankle within sight.
