I'm taking care of my BF's snakes (about 30 or so...) while he's out of town. In the past TWO weeks FIVE pythons have died!! They all seemed fine and then the next day they were dead. They all died several days apart, not all at the same time. WHY ARE THEY DYING?! What would cause a seemingly healthy snake to just die?? Any, ANY help and advice would be so very helpful! Please reply if anyone knows what could be causing this and HOW i can keep anymore from dying.
