My ball tried to eat a mouse and got halfway done, held it there for 2 hours and then finally regergitated it. Since then he's been "yawning" non-stop and seems uncomfortable. He hisses at me when I come near him (which he never did before) and he's not very active. He has eaten once since then but his lower jaw now sits on a slight diagonal. I don't know what to do. Can someone help me and him out?? Thanks!
