ok guys if you look above i made this rough sketch for what i was thinking to enclose a snake rack with 2x4s and pallet boards. I was thinking a panel type or oil based heater for the section that has the heater but i am concerned about fire.

this is not to scale! its a rough draft and i suck at drawing but i hope it helps you help me.

as you can see there is a door to help hold in heat.

i was thinking of building this around the large 5 drawer open side design from animal plastics. (i wouldn't mind a female cause they get huge)

any thoughts, potential hazards or opinions welcome .

Thanks
