My dad and I are planning on building a...well, not a rack exactly (my parents are still wildly against the idea of keeping any animal in plastic tubs, lol) but it's similar to...anyways, it'll be built out of 2''x4''s as support, melamine so the back's a solid color, and clear plexiglass for the front and sides...now. The way we have it designed, it's impossible to get belly heat--for BPs, is back heat alright?

I just spent like an hour working on a diagram...it'll be front opening with individual doors and latches. I've included three possible versions, with three different possible sizes for the big adults. It's in proportion, so...yeah. Could you tell me which one you like best?
