there are a couple of no kill shelters in Western Australia. but most of them pick and choose who will live or not. If there is anything wronge with a cat or kitten they put it down as it can spread disease to the other cats and as most of them are self funded or rely on donations they cannot keep sick animals, they have to keep things cost affective and sick animals take away any small profit they make. it is very sad but it is a fact of life
