I personally would not have 100 per cent outdoor kitties, and i do agree spaying-neutering is a must especially if they are outdoor most of the time.
Maybe coolbabe22 situation is not ideal for the kitties, but in reality they probably would have been put to sleep, as we all well know there are more kitties than furever loving homes available, it may not be ideal to us, but they are sheltered, feed and loved from what she says, so i guess you just have to weigh that all up.
