I have no clue about the poop stain thing (don't think I wanna know)
I have two that were donated to our rescue.....one is the 4 foot double door condo....the other is shorter and taller...both came with heat and light....
EXCELLENT humidity and perfect temps....the ONLY two enclosures I don't have to constantly mist and adjust..
AND these are the cages that the ONLY two females to breed for me are kept in......
i personally LOVE these cages....I have heard bad things...but this is my personal experience....
