ok, so i recently purchased 3 used cages comstructed of PVC sheets. these are nice cages crafted very well. the only problem is they have dark stains all over the floors. it truely looks like the feces stained the floors.
is this a common problem with PVC cages? i have several neo cages and have never had this problem. i will not name the company that made these cages unless it becomes relavant to the discussion
