Cool; I thought of putting him into my BP rack, but he is already on the larger size for the tubs and would be outgrowing it in the near future anyway. This cage is large enough for awhile yet; I plan on building a melamine box type cage for him in the next few years, when he seems to be outgrowing this one. I only plan on having one BCI so a rack would not be needed; that is an ADORABLE boa pic by the way!!
