do you have a garage or basement? if so, you could set up a little heater or lamp for her in there so she can keep warm till spring, when she'll most likely find her own way out.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
