I’m at a friend’s place and the cat keeps bringing in dead (or half-dead) animals into the house. It’s my understanding that cats think we are big, helpless kittens that don’t know how to hunt. Hence, they think they are doing us a favour.
It seems like a few mice actually escaped and found refuge in some walls in the house, so these “presents” are actually more than just annoying (and smelly if the dead animal ends up behind the couch).
I think the problem with domestic cats is not the color of their passport, but the fact they are not subject to pressures limiting predators in the wild.
They have:
a) permanent shelter b) constant access to food
So while others animals are starving and being eaten, the cat just goes out there every day and kills everything it can find, and if it can’t find anything, it goes back and has a full meal, and it does this every day for most of its very long life no matter how much food is available or how cold it gets.
That’s the reason wildcats are not a problem, they have small stable populations and barely interact with humans and domestic cats.
“Modern” Wildcats have been in all of Europe for at least 300k years, so they were just another predator species among many others.
