Hi. I have a metal chain link cage perfect for most sizes of critters known to be city dwellers; incl cats, dogs, squirrels, racoons, birds and anything else needing to be caged, penned, transported, or needing a time-out space of their own. And it folds up flat from a rectangle 36" long by 21" wide by 28" tall complete with a large door that has a latch that can be locked. Asking $30 but will consider reasonable offers as i would like to move this item quickly. Thanks! P.S. i do not know why my photos are sideways and upside down. Ill work on those.
