Don’t worry about feral cats. Worry about feral people.
You are ignorant of the situation. Dogs hurt and kill more people that cats.....
I was attacked by a feral tomcat about 18 years ago, in my own yard. It couldn’t be located, so I had the series of rabies shots. Its behavior was entirely consistent with some sort of major brain/mental disorder. I eventually spotted it again months later, so it wasn’t rabid, but it was truly vicious, and went into attack mode like a crazed pit bull — it clearly couldn’t think about anything except trying to kill me. I got hold of one of its front legs and flung it into a cinderblock wall . . . and it came right back at me. Still have scars on my ankle from that incident — blood was spurting out like crazy, and I tied a tourniquet around my ankle and drove myself to the emergency room.
But I’m STILL a “touchy feely bleeding heart” when it comes to feral kitties, and prefer to see a trap-spay-release strategy employed. I keep food out on the porch for my own kitties, two of whom enjoy snacking outside (one is a former feral who I snagged and spayed just as she was coming into heat the first time). I keep a watch on what’s eating the food, and make sure any cats who are patronizing my free kitty restaurant get caught and fixed (and rabies-shotted) if they aren’t already. A few years back, a couple of my irresponsible neighbors had their cats disappear for a few days and turn up again fixed.
