I don't remember seeing this... I personally use one stack of three tubs with hardware cloth for ventilation for mice, but not for hedgies... I would think that'd be a pain unstacking everything when you need to get to each cage every day.
we are just trying to figure out a way to minimize space. as of now we have a room dedicated to our little critters and we are planning on moving so we may not have a whole spare room for them. SOOO we are looking for ways to save space if need be any other space saving ideas for me?
The first two pics shown are of that tub size, and the basic setups. If you scroll down a bit, there's a picture of what Deneen's barn looked like previously. The black and grey shelving fits three tubs. The only problem is heating, if you use that you'd need to use a space heater to heat the whole room.
