Is there something special about alligator lizards (Elgaria multicarinata (Gerrhonotus multicarinatus)) and water dishes that creates an irresistible urge to defecate in said water?

I have set two separate water dishes in the terrarium to facilitate easy access to water and each day I find that one or both have lizard feces in them. This usually occurs after one of them "bathes."
Is there something I'm missing? Too much traffic (kids walking past the terrarium), changing said water dishes daily because of this fouling of it, the overhead light going on and off via a timer (off at 5pm, on at 7am), general noise from the HVAC blower unit (across the room)?
I've known of one lizard (a skink) that super-stressed whenever one of the kids would handle him and thus relieve himself in their hands. That was his "last-stand" option but we're not handling either of these.
Thanks for any leads.

Maybe the water helps them relax. Would you have us believe you yourself haven't pooped in your bathtub? Emotion: smile
Lots of reptiles do this. My box turtles do it. Iguanas do it. Monitors do it. I don't know if many, or any, desert reptiles do though probably because they don't normally have access to standing water in the first place.

I would hope to have you believe I don't poop to begin with. Emotion: wink

Now that you mention it, my box turtles did have that nasty habit which explains why I'd buried those memories deep within my subconscious. My recent experiences with a garter snakes, two leopard geckos, and a clutch of chameleons simply didn't prepare me well enough for larger reptilian habits about standing water especially that which they would drink from. /shudder

Thanks, Chris.
