So I plan on getting a corn snake in the end of July and I have a few questions! 1- What would be the best heat source? 2- If i feed it f/t mice, do they come in different sizes? Because I know your suppose to increase the size as the snake grows 3- Is aspen a good bedding? 4- Would a local reptile expo have corn snakes for sale (i would imagine they would...) 5- Do they always need a moist hide? Or just for shedding? And how often do they shed?
