> Other places maybe not so much...

You probably don't notice them, all little birds, insects, lizards, hedgehogs (I saw a cat mauling one once, same with lizards and birds),..

Actually, in my city, near woods, there's a small outdoor refuge for "wild cats" as the woman I talked to call them. She was feeding them, so I wonder how wild they are and how much they harm the local ecosystem, on top of all the other pets

I think there's an unhealthy addiction and love for pets. If you like animals, you could let them live normally in their natural habitat, and observe them once in a while. I hope this mentality will change
