Half my smaller snakes periodically flood their tubs by sitting in the water dish. I ended up bumping the worst offenders up to bigger tubs to try and prevent the flooding/provide a dry area until I go to clean them out. My calico pastel has to have his paper changed twice a day because his absolute favorite place to be is inside his water bowl. I've checked him over for mites more times than I can count and nothing. He just seems to really like his water bowl.

Weirdo.
