Nobody is denying that cats are wild animals. The point is that they are uniquely capable hunters that can unilaterally exterminate the small fauna in a region.
I mean maybe your cat in particular is lazy and doesn’t hunt, but most cats do. For instance, house-cats kill 3.7 billion birds annually.
My cat is old, too, and he mostly doesn’t kill anything when I let him in the backyard. But that is not the norm for most cats, and people need to be aware.
