great stories, i'm literally laughing out loud.
That's a good example of the intelligence of chameleons. They aren't super-smart, but they are quite clever in the ways they need to survive.
My male veiled can smell the female right next to him, or she/he are communicating through the tell-tale "low frequency vibrations". He scratches at the lights sometimes, incandescant and fluorescant, because he sees them as a way out. That shows he is smart in the way that he doesn't claw at a random spot to get out, and that he looks for tunnels/holes/doorways. He also comes right up to the front of his cage (where the door is) when I am in the room, because he knows I might open it up for cleaning/misting/feeding.
The cage closest to the feeders and supplements (all in one corner) is home to one of the females, and whenever I fiddle around with things there, she will come up to the door and wait for food. Other times she looks at me like she's wanting food, but she doesn't come right up and demand it like that. She knows when i'm collecting stuff from a containder or i'm shaking something up (supplements) that food is coming!
I have never seen him attack his hygrometer, however! It is in a shaded area, like someone suggested to do, which sounds very logical to do.
