I purchased this for my hamsters as a play pen and temporary home until a larger cage arrived. My hamster proceeded to chew a hole in the side of this so was swiftly removed! I am using this now in my wardrobe as shelving for light items and it is brilliant. It is very easy to put together and sturdy when built. It is huge when put together fully. I would advise to maybe not use this as a pet playpen; the plastic panels are a little too flimsy and easy for teeth to get through but as storage, it is ideal.
