Originally I wanted to display them but its a little hard on the animals when they're out in the open. vivs are a little difficult to keep maintained and looking nice too. Our cat stresses the ones in the glass terrariums to death, Lol. I think I mentioned that in a previous reply, but yeah. I do like the looks of the PVCs, especially since they come in shelves as well, the stupid cat won't be able to bother them that way.
One day I hope to have a big reptile room.
Ive seen some rack systems that are pretty nice, but I recently heard a horror story about some yahoo who didn't have a therm regulator on his heat tape and literally cooked all of his snakes in the rack. That scared the hell out of me. Poor little things.
I'm thinking I'd like to breed these boas when they're big enough here in a couple years though. Might consider a rack for that and also for when the babies will be born. They'll have a little hatchling rack until I can find homes for them.
