What a shame that would be. Most cats are too easily semi domesticated. The lounge lizard sitting with me now though wants no part of ever having any part of returning to his roots. Hunting little frogs out by the pond, but only if I sit on the dock providing security, is as far as he or any of the rest of my gang want to walk on the wild side.
I have 4 house cats and I doubt that would kill anything. A mouse could probably take over their food bowl.
