Don't know if this helps or not, but our Panther Cham is also about 4 months old and eats about 15 or so crickets a day! Each time you mist it should be for at least 5 min. at a time. Hope he gets better soon!
I agree with you Kenya! You tried to give him a better life while he was living, and in the end that is what matters. You have every right to feel sad and feel a loss from this little guy's death. I'm glad their are people out there like you, that try and help animals that some do not want to...
