this just happened to me...... i put him near the light bulb and that made him perk right up!!!! he is now ok :) starting to open eyes and walk around his cage :) who new something like this could be solved with such a simple solution!!!
my 5 month old cham eats about 15 crickets every 2 days
i give him 5 extra just in case he is extra hungry : )
feel free to give them all they want or need
