Well...I'll tell ya what I'm looking for in a BP enclosure that is "not normal"...
I need a rack system to hold multiple animals in a relatively small space. I prefer tubs in racks for ease of maintenance and comfort for the animals. HOWever...they are ugly to look at from the outside.
BP's aren't "display" animals anyhow. SO....I'd like a "furniture-quality" rack/cabinet that can be placed in the living area of the home....with solid doors that close and lock so guests coming into the home are competely unaware that snakes are inside. When no one is expected...the doors can be opened and slid back out of the way (like a TV armoir) so I can see the tubs as I wish and get occasional glimpses of the shy lurkers within.
Inside should be shelves for several snakes (perhaps a breeding pair and their babies each housed in their own tubs) and some storage space as well for cleaning supplies and such.
