I love this cage when it comes to size. I have 3 ferrets that needed a large enclosure and this does the job. However the ramps are extremely slippery so it’s difficult for them to travel up 4 of them and the floors are also slippery hard plastic. I ended up spending a couple hours creating felt covers for the e floors and gripped flooring on all the ramps. Much better now.
Also, some pieces were slightly warped and extremely difficult to line up and connect. I had to hammer one door into its slots and work to mend the side walls to line up properly.
Overall, does the job and is spacious for 3 ferrets.
