I bet she is there, hiding somewhere, I have had rabbits escape at the rescue here some for 3 days but they have always stayed in the garden and I have always caught them in the end, even the tricky ones!! I use a fishing landing net to catch them, or i open up a circular run and with the help of someone else i round them up! I have also caught them by putting a tunnel out in the garden with one end blocked, wait on them nipping in it and close off the other end quick :lol:
so don't give up and keep watching for her. XXXX I hope you find her really soon.
btw, she will survive the cold and won't go hungry. xx
