Are you giving her a variety of foods? What are you gut loading your crickets with? It could be a number of things but the most common for healthy chameleons is if they don't get a different variety of food, they get bored this is my input on this but hopefully a more experienced member can help you out
gutt loading with fresh veggies and fruit. couple different worms. she's active, looks healthy. i was thinking she may be bored with them. just seems like she would eventully start eating them again. i'm clueless!
