Is anyone using a showcase cage or know of anyone who is? I was sent a link to their site and like the look of these habitats. I want to find a nice home for my Russian but would prefer to get something that provides ventilation and safety. I have a saint Bernard and building something tall enough that I can guarantee she can't get in, means that I have trouble comfortably working in it. I really just want something easy to work with that will hold up.
