He's almost a year and a half old. I think he was about four months old in the first picture. He was kind of small for his age initially then took off. He gets a lot of outside time. I usually use his smaller cage with a Hibiscus in it and sometimes I let him wander around with the cage open (watching him closely of course). He hasn't been out much in the last two weeks because the temps here in Indiana have been too hot even for chameleons
