can you tell us more about your chameleon? What type is he? How old is he? What’s his habitat like?
Without knowing the full picture, here are a few things to be mindful of:
1. crickets will eat anything, even your pet. so if there are crickets on the loose in your chameleon’s cage, try to get them out of there.
2. hopefully your chameleon is just being picky. But if it’s a loss of appetite, then that may be a sign that he/she isn’t feeling well. So keep a close eye on his behavior (lethargy, abnormal sleep patterns, erratic movements).
