This is a well-made, sturdy cage. I have purchased two. I use one for two chinchillas.  There is lots of room for them, shelves for them to race up and down and enough space for a large exercise wheel.  The plastic pan is large enough to catch their waste and is easy to clean.  The second cage, I gave to my grandson for his very active ferret.  That cage has a hammock for the ferret as well as plenty of room for his food and his toys.  I especially like the easy  to open and to secure doors which make it easy to access the inside of the cage but lock it securely to protect my escape-prone chinch.

I replaced two of the shelves and the ramps with plywood since a chinch is prone to chew plastic.
