Coming in this thread a bit late but...
I've had my snakes almost a year and my local breeder said to feed in paper bags to give them privacy and to prevent food aggression.
Now I know from reading a few threads that feeding in there cage is a better option.(not that they seemed to care about eating in bags) My only concern is, what if they get the rodent covered in cypress mulch? I haven't found an answer for that one.
Thanks
