I am *pretty* sure it's a girl, but I didn't get close enough to actually check. I hope I can tame her and bring her into the warm house. If she's actually a she, her name is Ginny, after the little girl wildcat in the James Herriott book "James Harriott's cat stories". If she's a boy, his name will be Ollie!
Having said that, who knows if I will ever see the poor skinny little thing again. I hope she enjoyed her meal, and it helped her out a bit!
