We dont keep a waiting list sadly, I was discussing this with the rescue's local RSPCA, as I was going to suggest starting one, and they actually talked me out of it, they found it wasn't effective. I have just had a call from Social Services about 2 cats, but I am up to 4 and my comfortable maximum is 5, they are mum and son so couldnt be split. Gave them a couple of numbers, and fingers crossed for them.
