I've just phoned the RSPCA. Sadly, as anticipated, they will neither give her to another rescue nor rehome her. According to the lady I spoke with the vet has said she is very sick (heart problems, kidney failure, hyperthyroid) and 'wouldn't last a month'. If she is not claimed they will PTS. I have offered to take her and I've told them about Truman that came to me from Brent Knoll two years ago who was found in similar circumstances and that I've been home checked by RSPCA in Leicester. I've left my name and number but don't expect to hear from them.
