Rory likes to go out and about. I had his area set up to let him climb to the ceiling in his nook, but he escaped 4 times! Wasn't sure if he just fell and couldn't get back or if it was on purpose.... Then I re-made his enclosure to be completely screened in for about 6 feet of height.
This was actually a few months ago (like Nov. 2014), but I am really bad at keeping up with online stuff!
