I actually left them last night because I did not work and would not be up until early afternoon and since it was his first night I thought he may eat early today. However when I got up almost all of them were dead! I heard from his breeder and he had been free ranging for his food so I released a dozen or so into his cage and he hunted them down! I am going to try to train him to cup feed so I can keep track of what he eats though.
