Boy, this guy has a serious condition if he keeps throwing up skulls. Maybe he is part owl? Owls will throw up the bones of their prey in little balls of organic matter. They spit up the skulls of mice and smaller birds and voles and snakes and so on.
I don’t get the sense, though, that they’d eat more than one at a time – that there would be a torrent of small animal skulls. But I don’t know, of course, I don’t know.
