“Hunting behavior in cats is very controversial, especially if the prey is songbirds or endangered rodent species. Some cats hunt, some cats don’t, and it has more to do with what a cat learned from his mother than from the rumbling in his belly. Plenty of well-fed cats are very active hunters.”
My comment: Controversial? It certainly should not be. Cats are a domesticated pet species and as such should never be allowed to roam outdoors. Their presence outdoors creates an environmental and ecological problem which should be dealt with by confinement or eradication.
Attempting to treat it as an animal welfare issue by enabling cat colonies perpetuates the environmental and ecological problem, ie, pet predation on our native fauna, and is morally reprehensible.
