If they even do it.. The catch, neuter, give rabies shots, and then release them back in the same spot they were caught. We are now starting to have Rabies increases in our county of Cumberland.. The local government where I live don't even set traps.. They leave it up to what I call the Cat Ladies in the area to catch them.. The one in our development does nothing.. So we have cats all over the place now.. As you know they do kill a lot of song birds and birds that eat insects... Local governments are doing nothing...Some of the ones that don't get the rabies shots are going to create a rabies epidemic .. Also you have people who mean well by feeding them on the outside.. In comes the skunks and coon to eat out of the dishes that can cause a epidemic of rabies..Plus just the catch and release is just not logcial to begin with in the first place.. Sometimes you wish a few coyotes would move into your development and clean house..By the way I do like cats.. Cats that are taken care of in the house by their masters and don't let them roam... My daughter had a few and they act just like a dog if you get a smart one...
