I can’t remember the last time I read about a cat jumping over a fence and mauling some child (although I did find a half mouse on the doorstep the other morning which I suspect was a present from the neighbors cat)
My uncle had a cat that was vicious. If would attack anyone who came near his house. The mailman refused to deliver so he had to pick his mail up at the post office. Certainly not deadly but they are not all nice animals. I've been at houses where cats would just come up and bite people for no apparent reason.
