Abstract: A pet cage cover for covering a pet cage comprises a top panel and a plurality of side panels. The top panel and the side panels define a space for receiving the pet cage. Each of the side panels corresponds to one sidewall of the pet cage in shape and size and can be independently rolled up, so that all of the sidewalls of the pet cage can be exposed by the pet cage cover. Therefore, no matter on which sidewall the door or multiple doors of the pet cage are located, they can be always conveniently exposed by rolling up the corresponding side panel on the cage cover, so that the door or multiple doors are conveniently accessible even with the pet cage cover on. To provide desired covering function, each pair of adjacent side panels can be detachably connected along their side edges with, for example, a zipper or Velcro.
