After spending over $200.00 on this product, I was extremely excited to get my ferrets into their new home. However, upon receiving the cage, I noticed that most of the cage parts were warped. A "no tools" required assembly turned into a "hammer for 3 hours to get the parts to fit together" assembly. Even now that it is together, the doors jam. The ramps also are hard to hook onto the bars and do not feel very sturdy. Other than that, the cage gives my babies way more space and is WAY easier to clean than a standard ferret cage. Bottom line is its a good design, but you may not receive something worth what you payed for.
