My baby RTB ate today! I tried a f/t rat pinkie but he struck at it and then let go of it and wouldn't strike again So I went to town and got him a small mouse and he hit that so fast I jumped! (The guy that we got him from said he hadn't eaten for a week before we got him). For such a tiny little thing, I can see how strong he is already! Yes, he will be switched to pre-killed the next feeding and switched over to f/t ASAP.
