After my father died, I was staying at a duplex he owned in the country. The renters in the other half were young and irresponsible. They had a cat which ran loose and was not fed very well. Almost every day it killed a songbird, chipmunk or the like. I was angry, but couldn’t really blame the hungry cat. Cats should not run loose except where they are needed to keep rats under control
I agree, cats killing songbirds can be a problem. Mine are good now and only kill mice (and not nearly enough of those). They just watch rabbits (it would be nice if they at least chased them). They don’t pay much attention to birds although it was different when they were younger and mostly indoors. Lost a couple finches then, not a lot but still disturbing.
