Thanks for your wonderful replies and well wishes! Now that she has calmed down a little, I got a good look at her. By the way she acts, she looks like she is in heat however she doesn't look to be more than 5 months old. How old does a female have to be before she gets her first heat? I'm not sure...

I'm glad I caught her when I did. It snowed last night and she would have frozen to death.
