I bought this for my ancient old cat Susie whogets lost even in the house. She loves the little bed covering and really appreciates that the shelves can be adjusted just for her. She has a hard time jumping, but being able to adjust the shelves means she can get a little exercise without hurting herself. The double, self-locking doors were an unexpected bonus, making it very easy to care for Susie without having to work to hard to reach her litterbox and feeders. It was very easy to assemble and looks great. It is an excellent cat cage.
