I use a vision cage.Not sure of the dimensions but it's will house a adult BP. I know its 12-14" high. Which you don't need height for a bp. Heat source is a under tank heater w/ hide on hot side. water bowl on cool bedding is news paper. She switches from hide which stays around 85 during day and goes to cool side when she warms up to under newspaper. I really don't know why i have hide in there if there is a paper hole in hide she'll gon= under newspaper anyway. She weighed 987g now only 935.I know i'm i'm just jumping the gun here but really wanted her over 1700 to breed this November -December but at this rate i'll be looking at the following season thanks again.
