This 4-tier metal cat cage is an indoor enclosure for households with 2-3 cats, kittens or small animals. It is made with Q195 steel and thicker steel wire in a modular design that stays steady during active movement. The four tiers create a vertical playground for climbing, lounging and exploring without taking up extra floor area, and the structure reduces wobbling for daily use. The overall size is 55 x 55 x 55 in, and the product weighs 50.59 lbs. Upgraded connectors are designed to withstand jumping impact and repeated use with less cracking and deformation. Three doors with locks provide access and help keep cats secure. The ladder-free design lets cats climb along the cage walls, and the detachable panels allow a Diy setup that can be combined with cat trees, toys and hammocks. Wipe the wires clean as needed. The package includes the cage only and does not include pet toys or other accessories.
