Three levels divide the enclosure into a rest area, a play area and a feeding or litter area, which is the arrangement that lets one to three cats live in a cage without the food ending up next to the tray. Panels detach, so the height can be reduced for a kitten and built back up later. Overall it stands about 29 x 29 x 42 in with each panel rated around 11 lbs, and the cage weighs roughly 20 lbs in PP and metal wire. A hammer and user guide come in the box for assembly.
