I woke up this morning and fed my chameleon like always. He usually attacks the crickets as soon as they're in the cage, (he has a huge appetite) but today he only ate maybe five and moved very slow. Just a few minutes ago I misted his cage, and he drank for a second, but then stopped and started making a weird noise. It sounded sort of like a little cough or a wheeze. He did it six times in a row and his chin would puff up each time he did it. Can anyone tell me what this means?
