| Hi sp,
dont fret too much until the post arrives, they can go weeks in a bag.
its unlikely it will die, it will be dehydrated and looking for some heat when she arrives.
think positive and stop stressing so much, it is beyond your control at this stage just prepare for the arrival so the snake is immediately put in a tank it can be left alone for a week or so. hides heat and water.
any new herper take note, do not send live animals through the post system. Ncherps was being tactful compared to what a lot of experienced herps were thinking, don't let that put you off. Understand that and learn from the experience. Flying them isnt foolproof and things can go wrong there too, freighting of snakes shouldnt be taken lightly. |
