I've noticed that some have put the 'doorway' in their hides in the top so our friends can crawl in and out through the top instead of a hole in the side of the hide. Any pros/cons? Good/Bad for that? Do yours seem to like the holes in either one place or another?? Just got some new ones since Eddie has outgrown his first set.... wondering if I should keep his doors on the side or try putting them in the top for a change for the better???
