Depending on how big, or small the enclosure.
It doesn?t create much, if any heat besides the actual area it covers. (Winter mainly)
Also I found the snakes don't seem to ever leave the hide on the warm spot and you never see them.
I have used them with critter cages, but prefer heating from the top.
I run a heat strip along the shelf. The click-clacks sit on top with heat source at the back. I put a perch in as well up the warm end.
It works for me.
