This cat enclosure has many nice features: the pull out bottom tray, 3 adjustable perches, 1 bedding pad, four doors in front for easy access, casters for ease of moving, plus caster locks. And the cage structure itself is all one piece for easy assembly and storage. (Of course, it's much easier to erect if you have two people setting it up.) I also purchased one small and one medium attachable feeding dish. Very handy and secure.
