i think i heard a weezing or a squeaking coming from my snakes cage just now. it sounded kind of like a very very quite creaking door. my snakes temps are good, and it is not too moist, between 55 and 65 % humidity. it seemed to stop for a minute or 2 but then started again. can snakes snore? or is this a sign of lung problems. what should i do? (before going to a vet). i couldnt get an apt. for days. can i take em to the animal e.r.????
