Eating mouse tail first?

[Timelugia]

Have you ever heard of a BP choking or causing serious damage to themselves because they tried to eat backwards? I haven't, but with the way Bix was going at that thing in such a weird manner...I basically didn't breathe til he put the mouse down so I could take it out of the tank.

There is one definite disadvantage to eating it backward. My ball proved this last week when she tried to eat a mouse backward and somehow managed to squeeze its bladder. She spilled pee over the substrate and I assume in her mouth. She was not happy to say the least.
I don't know if that's the only downside, but snakes do seem to favor head first, so I imagine there are evolutionary advantages.
