The Wall Barrell, by ItchyKnee is a wall-mounted cylinder intended for cats to jump around, on and in. The outer shell is upholstered in wool, cotton or corduroy and the interior is lined with either faux fur or wool. It comes in 3 sizes ranging from 13.5" long to 40.5" long, all with a diameter of 12.5". The idea is to satisfy your cats natural tendency to want to hide and climb into strange places. The barrel can also be a place to sleep since its hidden from view, while also providing a nice lookout.
