Ive attempted to feed my baby ball (around 4 months old) 2 times now. The first time he struck at the adult mouse within seconds of me dangling and tried to eat it for about 2-1/2 hours and then spit it out. The second time I tried again with a hopper and it took him a little longer to strike at it, but he eventually did and again it took him about 2-1/2 hrs to try and swallow it, until he spit it out. Both times it seemed like he didn't know how to swallow it, but the second feeding especially made me believe he didn't know how to eat it because he would spit it out and then go back and try again 3 more times. What does this mean?
