If that's a recent feces/urate in post 26 then your chameleon is dehydrated. I would set up a dripper and make sure that when you mist you mist it for long enough to stimulate it to drink. A thirsty chameleon sometimes won't eat. The dripper can be a deli cup or plastic solo type drinking glass with a tiny hole in the bottom so it drips at the rate of one or two drips e second. Make sure it drips onto a leaf.
While it's mouth is opening and shutting as it's drinking stick a cricket head first into it's mouth so it's between the teeth when he closes his mouth. This may stimulate him to eat. Let me know how this goes!
