Creatures of habit.

I've been cleaning cages for the past few weeks and been trying a new substrate. It's coated with activated charcoal so it's very dark. I've noticed the snakes are a little leery about it. They head to the vines when I first put them back in. For some it's taken a couple days to finally try the new stuff out. The Northwesterns are on day six and only a couple out of the 8 have tried it out. Such funny little snakes.
