Did you hear about the Bearded Dragons who tend to have seizures and the like from sitting on those half-logs? When those nasty things are heated up(such as by a HEAT LAMP, HMM), it seems they emit some sort of chemical(possibly from the coloring, the treatment, I don't know), which causes seizures.

They don't hide under half-log hides made by Zoomed in the wild. Go build a termite mound or get some cork bark for them to hide under if you want to be "natural".

All of my snakes are my pets first(50 plus) and they are kept happily and properly in an easily-cleaned/easily-heated environment(ie tub in a rack heated with flexwatt).
