This 41 x 14 x 55 inch cat cage stacks four tiers with three front doors, giving your cat separate zones to play, rest, and use the included litter box without cluttering your floor plan. Anti-rust, powder-coated metal wire forms the frame, and thickened PVC plastic boards support each level so shelves don't flex underneath your cat; wire spacing of about 1/2 inch is tight enough for cats to climb and jump without catching a paw. This cage is sized for average cats and isn't recommended for large or overweight cats. A ramp ladder connects the tiers so your cat can move between levels on its own, and wide door openings make it easy for your cat to come out and interact with you. The frame weighs only about 22.5 pounds, so you can set it up indoors, on a patio, or bring it along when you travel. It ships with a hammock, anti-slip mats, and a litter box included.
