@niclas @bonifartius birds can fly -BUT...
At night, the cat is in advantage, when the birds sleep. Not sure about most birds night vision, either. Young birds in flight training often fall victim to cats, too.
And there are a lot of species that suffer from a high cat density, too. Like lizards, mantis...
Also in countries like new zealand the endemic species are not used to predators like cats, they do not escape.
@bonifartius @niclas i prefer having some side catch over using poison for mouse control.
I guess cat birth control is crucial. Feral cats are terrible to the environment.
@Sibylle
Locality is a very good point, I give you that. Fall victims, tough but life isn't fair. No star for trying, in nature.
@bonifartius
Since birds (generally) fly, they have a fair advantage over cats.
Also, I had a house cat that was so "humanized" that after catching a mouse, it played with it for a while, then let the mouse and go to get some food from us humans. "Killing? Eating raw meat?? ME???"
