Cal King in Eco Earth

Some folks in the kingsnake forum suggested that I give my California Kingsnake some substrate in which to dig. The popular choice seemed to be Eco Earth, and I put an entire brick in one side of my kingsnake's enclosure. He likes digging in this substrate, and this picture shows him emerging from a favorite hole. Prior to his moving through that hole, he'd been in the bottom of the log hide, and one coil is still visible there.
