Four storeys stacked in a 16-inch square, which gives four separate hideaways in the floor space of one. A bamboo mat lines the interior, which stays cool in a way fabric does not and matters in a summer room. Unstack it and the same unit works as a four-level cat tree. A large sisal board handles the claws, and both the cover and the perch come off for washing.
