I saw something similar when a snake swallowed a baby mouse, the mouse was trying to claw its way out of the snakes mouth, hten you could see its little claws pushing against the insides of the snakes throat for the first inch or so. Then the little bugger perished. The End.
Only thing is, this article seems to be from a legit newspaper site from the UK.. So, I am presuming it was real.. One would hope the reporters are not that gullible..
