So my whole platform idea backfired on me...I was hoping the snakes would use them to bask on top of them...but instead, they like the little cave like cubbies underneath so much, they won't come out of them! They have been inside of them since I put them in there! And it's dark...so now I can't see the snakes. I have to take a flash light and peek in there now and again to make sure everyone is okay. I ended up taking the second bin off the top in Cee Cee's enclosure...so she just has one bin in there now. She and Seeley refuse to climb to the top...so I figure maybe with just one bin, they may actually come out from their little cave and try to bask on top of the bin at some point .
