**Stupid question I need to ask**

[Redneck_Crow]

Pretty much any cooties in a snake's water bowl are going to come from the snake. The snake already has them. I go for keeping my snake's bowls visibly clean. I would feel fine with washing bowls every few weeks like Simple Man does. I've just got a routine that I superduper clean the snake tubs every couple of weeks and get the water bowls at the same time. That is dictated more by my personal schedule than need. When I get more snakes it will probably be adjusted.

I treat the water bowls like the rest of the cage. Visible mess or stink get immediate attention. The rest gets cleaned every couple of weeks and I wouldn't feel bad if it went longer.
