Lots of good responses to the OP on bathing.

One thing I did not see - never use water that has gone through the hot water heater for drinking. This goes for animals, reptiles, humans, everything.

Drinking water should only come from the COLD water side and let it run for a bit before using it. If you're worried about the cold temperature for a reptile, fill up a gallon jug and let it sit until it warms up before using it.
