I have been taking my iggys outside to get sun, and i was wanting to know is there a thing as "too much sun". We carry there cage outside, and if the sun is good for them, i can leave it out there for a long time. I just don't want to give them to much.
Just provide shade for them to get out of the sun. I left Zair out for an entire summer a couple of years ago...even during the night. Don't do this with the babies, but as long as you're home - you can provide moderately supervised outdoor time all day long...:-)
