I have mixed thoughts on this. I know that a well fed cat is a fertile cat, so in a way it's like contributing to the problem if you are feeding but not getting them fixed. I feed ferals in my neighborhood, but I have taken all but one in to get fixed. The only one left is Corktwo and as soon as I can scrape up some money he will get taken in too. So I guess I think if you aren't willing to take them in to get fixed then don't feed them. As mean as it sounds cats are self sufficent when it comes to food, well feral cats are. But it's always a good idea to leave some fresh water outside for them. Just my 2 cents.
