This is a very straight forward question.. what is a lung wash? Besides my vet refusing to explain what a lung wash was, I can find nothing of what it actually is. All I know is that if it's done I'm looking at a bill worth more then I want to say.... can someone please explain this, And tell me, is It really going to help with an RI or just put my snakes life in more danger then what it's already been put in..
