I can't move around my yard at any time of day or night without disturbing a cat. They aren't chipped or tagged and there are no registration fees unlike dog ownership. There is no equivalent of a dog catcher or fines for people who let them wander.
I got a hefty fine for a chihuahua cross that bolted out the door a child left open and got a couple of blocks away before we noticed. A huge threat to humans and livestock that was.
My neighbours cats set up near permanent residence in our yard shitting Toxoplasmosis into my kids sandpit and killing native wildlife that would cost thousands of dollars in fines and/or a jail sentence if their owners did it and there is no recourse. I am surprised illegal baiting of them isn't more common.
