how much does a veild cham actually have to drink??

Veiled Chameleon come from areas that range from 4-80+ inches of rain annually.
They get a lot of moisture from the insects that they eat.
In hard times when the insect population is low they will eat leaves.
They can get moisture from this too.
A constant dripping water source and 1 misting a day(bare minimum) is good enough.

thanks makes sence
