We have owned many cages in our time and we currently had nice cages when we purchased these cages  I purchased 1 and we put it together and neither my husband or I could find one thing that we didn't like about it. They are built really well. Easy to put together. I loved the cage so much I purchased another one. I am going to replace all of my current cages with these. So easy to clean and have access to everything. The doors lock and unlock so easy. Sugar gliders are very messy eaters, but this wipes clean in about 2 minutes. I don't know what the coating is, but seems nothing sticks to it. So much room for my gliders as well  I highly recommend this cage for any animal that it works for. You won't regret it.
