Ok so ive heard of people putting their tegu's in a hibernation bin. They put hay and leaves in it. What type of leaves? also do i have to change the hay during hibernation? also do I mist of no? plus ive been lowering his light time hes now at 11hours a day. But He's only out on average about 1-2 hours basking and then he goes back to sleep. Also what size bin should i use? I'm going to use a bin because ill be finishing his enclosure during his hibernation. Thanks
