My chameleon hasn't eaten for over a week now and has been a lot more grumpy recently. I have been offering him his favourite food which is locusts but still no feeding response. He is over 2 years old now and their average lifespan is like 2-8 years. Could this be signs that he might be reaching the end of the road? He doesn't seem weaker so I hope not. His cage hasn't changed and he isn't about to shed. I know this is a frog forum but I figured someone might have answers.
