I am sure it varies from Cham to Cham.
I have never used them.
But too that point, I recently had changed my misting schedule, and my female became dehydrated. At this same time I saw her drinking more. I believe now she missed some days of getting a drink because of the change. She became thirstier so I saw her drinking, before she was drinking but not in front of me.
She adjusted and her poops look good.
Now I change slowly if I need to.
