We've got am 8 week old Dutch and I was wondering if this cage is big enough for her. As in, will she still need to be let out in a bigger area to exercise, or would this be sufficient? It's our old three-story condo of NIC cubes so it's 5 feet by 5 feet and 29" tall. She's so tiny she can crawl between the 2 inch grids! This is the "rough draft" and we'll put down nicer flooring in the next week or so. And am I missing anything? Thanks, guys!
