I would tend to agree here. A simple example is chams eating soil. Is this only in captivity ? Do chams have "natural remedies" they would know to go to the ground for? It would be nearly impossible to truly answer these, but as you mention we don't really know. Trips to the ground may be more common than we think. If it was a once in a while thing, like dogs eating grass, we may never see it in the wild. Though other animals have shown these behaviors.Agreed with your point, but klyde insisting that the only part that matters is where they sit most of the time is wrong. There is no solid proof either way that the bottom doesn't matter or matters. We don't know how it affects their immune system, comfort, etc. May not at all, may more than we think. Also, as most of us with chameleon experience know, chameleons do regularly travel to the ground.
