My youngest cat has killed at least one bird on his escapes outside. Mice, moles, lizards, all get left by the front door. I try to keep him in but sometimes he slips past me and runs off into the woods. He's a brat. I was holding a duckling for a pic the other day and he tried to bat it out of my hand. I had to kick him out of the room. But they don't try to get in the incubator. They just look and listen.mine likes mice but not chicks..
