I have a 1+ year old veiled cham. He is about 8 inches s to v and has never had problems in the past. He is usually a very calm cham but over the last few days he has been walking on the sides and bottom of the cage. NOTHING in the cage has changed. and one odd thing i noticed is he stands on his back legs and looks at the lights on top. the lights havnt moved in 2 months and has never done this before. i have heard people say they might be abloe to see themselves, but he hasnt done this for 2 months why now?
