My bearded dragon, Simber, hasn't wanted to eat his crickets for a week now. This strikes me as very odd because bearded dragons aren't often known to go off feed. He was eating perfectly fine for the last several months. I haven't changed anything about his cage, it is an Exo Terra 36x18x12 (Short Large), and his UV and basking lights are still functioning normally. He just seemed to completely stop eating. Is this normal? Or is a vet appointment in order?
