Go with a rack for the BP unless you want to make a display case out of it. But, being that you were already discussing the possibility of adding on, like others said, you may want to just stick with a rack. My BP rack is far greater in my thoughts than my PVC Cage Wall that displays my carpet pythons. The rack takes up a fraction of the space and houses 6 animals, where as my cage wall which essentially 4 ft x 6ft x 2ft houses 5 carpets and a Boa! Then again, these are larger animals with different requirements. Get the cage that suites your needs the best, but I can not reccommend the RBI BP rack enough!
