I recently called a reptile rescue near me and they have two red tail boas that I have put on hold till december 6 when I will be able to get there to get them. The male is 6 1/2 feet long @6 yrs. and the female is 7 1/2 feet @6+ yrs. I have a cage that is 4' tall X 2' deep X 6' wide. is this big enough for them? If not I can build them a bigger enclosure. pics to come soon(I hope) after they get here.
