Yes...my garters love to poop in a freshly cleaned water dish. I think it is their way of saying "Thank you for cleaning our dish faithful human servant...now chop chop! Clean it again!"

As other members have said...fasting before a shed really depends on the snake. Some of my garters refuse to eat right before a shed and others eat no problem. Cee Cee will usually even come out of hiding with her eyes all blue and eat. My babies and Possum do not seem to have a problem eating prior to shedding. Hermes and Seeley will not eat before a shed...sometimes they will not eat immediately after either.
