So I just picked up a nice 2 yr old male Cal King from the expo and he is doing good so far. In fact he just shed. What concerns me is that I keep catching him in his water bowl.

His temps are good at 85 and 77 and his humidity is at 36%. I check him for mites and there are none in the water bowl and I didn't see any on him at all. Do Kings just like to soak or could there be a problem that I'm not aware of?
