I could be wrong as I'm in this only about 2.5 years...but every time I get a new snake, they seem to inspect every aspect of their cage...including staring up at the heat lamps a bit. I think it's just normal curious behavior, checking things out. I read somewhere that a way to check for IBD is to flip the snake on it's back and if it can right itself without problem, it's fine.

But like I said, I'm pretty new to all of this...
