One more quick recommendation:
My snakes love to burrow in their bedding and since, like a heat rock, they then get really close to the heat pad which can sometimes get too hot, they risk burning themselves. Before I put the bedding in, I lay down a piece of repti-carpet. This helps to spread the heat and they don't go under it, so they are safe from getting burnt.
I am also concerned. My snakes love to crawl around the lip of the cage's lid. if you have a heat lamp up there. They may be able to get too close for their own good.
Just trying to keep your snake safe...
