this cock-up by the RSPCA does sound unfortunate, but I thought somebody should at least say a good word for the RSPCA. In my opinion they do a bloomin' good job, often in very difficult circumstances, and they tackle a huge number of cases of appalling animal cruelty and mistreatment. Like any large organisation there will be administrative cock-ups, incompetent staff and so on, but I've always been impressed by both the commitment and the knowledge of the RSPCA staff whom I've had contact with.
edit: ah, I've just seen that Kymba has made a similar point above
