You left her. And she is retaliating. I left mine for a week and she poop painted for the longest time. They DONT like change. They want to have everything on schedule.
Go back to routine. And be diligent. Handle her everyday. I have a new iguana and she is over a year old. The other one passed away after surgery.
Anyways This one I do my best to keep her on a schedule. And now if I'm late taking her to the bathroom, she comes looking for me. lol.
