Update from the person!

She said the snake hibernates through the winter and only comes out for a drink or two, so he's not fed that entire time. During the summer, he eats one full sized mouse per week. She said she has enough frozen mice to feed him for at least a year and everything would come with him. The tank is indeed a 10 gallon.

I don't know anything about snake hibernation =\ If he's been used to this for 6 years, is it safe to stop it? I would have him on proper heat and monitored temps year round...
