It finally warmed up enough for me to take Petri, my juvenile femal veiled, out into the sun. I figured I put her in a cardboard box with her favorite plant while I did the weekly cage cleaning outside. It seemed like she enjoyed it. It was about 75*f-80*f ouside. She got up to the highest point of her plant and stayed there. She was opening her mouth for long periods of time though, despite I just gave her a shower. So I don't think she was dehydrated. Her colors lightened up very much. Almost like the colors when she sleeps. She did manage to get out of the box when I wasn't looking and started sprinting across the lawn as I tried to catch her... Besides the mouth opening, I think she enjoyed the good hour that she was out there.
