Hi I have one veiled chameleon who has been staying on the ground for long periods of time. He is about a year old, his enclosure is 18 in wide, 18 in thick, and 36 in tall. Last night he slept on the ground and when he woke up today he's still on the ground. As far as care goes, his humidity rarely drops below 60% without my notice, I keep the temperature between 75 and 85 and feed him crickets with an occasional hornworm or meal worm. Just a week ago, he was an active little fella climbing about the tops of the cage on his leaves and stuff but the past couple days he's been acting extremely docile. Any thoughts or expertise would be appreciated. Thank you.
