These are fine cages for many species, but I do not recommend them for BDs. Their main faults are in the low height and the molded-in light wells. I have 3 of these cages, stacked, and I will make them work through experimentation and modification. If I were allowed a do-over, I would build my own enclosures (24" High), and I may still.
Showcase makes a fine enclosure, they just aren't well suited to this species.
I found other cage suppliers online, but most are melamine and shipping costs are prohibitive. Perhaps another member could steer you inthe right direction. My suggestion is to build your own. For the price of the Showcase you may even find a carpenter to build it for you.
