Actually I think I saw your post..you just got him right and it looks like one of his legs has a bow in it that might be from MBD probably because of poor husbandry from the pet store? Is that you? If so I'm really sorry to hear that your guy already has problems and you just got him. The sad thing is that MBD is really hard to treat and it can be an ongoing problem because many times not only has it effected the bones but also the internal organs and definitely can be costly with vet bills. Definitely see what your vet says, but even though you love him you might consider returning him and purchasing a healthy veiled from one of our sponsors. Sorry, just a thought
Regarding the doors you might be able to remove one and smash out the glass then hot glue or silicone screen to the frame in place of the glass. I actually did that with a full hood that was used for a fish tank. Part of it was glass and I broke the glass out and replaced it with screen. Worked really well.
