Perky is a mix of some sort, definatly NOT a BC lol she is only 12" tall, she fits the appearence description of a JRT but her attitude is all wronge, she has NO prey drive whatsoever, if I wanted I could put a gerbil on her head and she would not care, and she is afraid of my rabbit, plus she is super smart and has a really high attention span, non of these are JRT qualitys.
