I would avoid the outdoor enclosure, unless you can safely protect the Uro.. which is very difficult to do. You will need a screen to keep birds out, but then the screen will block beneficial uvb. Using a glass fish tank with a screen top will get too hot and basically cook the uro..

I used the uro dust twice a week, then down to once a week, sprinkled on the greens. Every day that ate it, their stools were little pellets or runny, or not very white urates.. i didnt feel comfortable using it after that. Many others have mentioned similar patterns of odd stool or behaviors.
