Oh, poor kitty. While you're looking for a home for her/him, perhaps you can build a temporary house just outside of yours - in a quiet place, or in the garage. Put some old - but clean blankets and food bowls there. She/he will soon feel secure with you around. If you have time, sit and talk and let her/ him come to you. Oh, I hope you can get her/him to a vet for a much needed treatment.

You can see here how we did it: http://67.15.70.205/talk/showthread.php?threadid=7761

Best of luck - and thank you so much for caring!
