The cage is very small data size is not accurate. With all stairways, the wheel and the hamster home can no longer live so I had to withdraw its li house. the pipes are thick enough that the hamster passes but they are willing maize. Our small rodents can still sneak it. Also my hamster has everything nibbled from day !!! The wheel is loud. My hamster can not sleep in my room. The bottle leaking a lot of sudden I have to put a pot instead. Compared to another cage on Amazon, it is cheaper I recommend this cage for the price. The delivery was quite fast, 3days waiting.
