I know my friend from the RSPCA says this is classic chucking out time of year as it gets cold and wet. The thing is he's really friendly and in pretty good health teeth look fine clawa slightly on long side but not too much. Lovely fur condition. He'd be a perfect house bunny, but if he is then someone would really love him and would have found him by now, or put their own lost pet signs up.
I think I'll keep him till his owners get him or until he finds the perfect forever home, or until I love him too much to part with him-whichever comes first.
