What you can do for airflow is if you have a fan point it downwards into that cage. Don’t blast your chameleon away but just enough to have a bit of airflow until you get another enclosure.
Oh my goodness! The drama had me on edge! The squeaking! The very first time I had to remove Grumpy (my first cham) from her enclosure, I knew zero and just grabbed her. She squeaked in distress.
