Well first let me say that from the pics it looks like it is a she, second, what you can do also is take it to the shower along with its plant or some stick stand and turn on the warm water and direct it to a wall so it can get a little bit wet from the splash and the warm vapor, this might trigger a faster drinking response and will help it poop along the way, that is what i do with both my chameleons and works like a charm, good luck
