摘要： The present invention is a pet cage having an upper cage member and a lower base member. The lower base member has at least two portions: a fixed portion and one or more adjustable portions that can be extended or collapsed as needed. The fixed portion comprises multiple sidewalls arranged in serial to form an enclosed structure except for an opening on one or more sides, where a lip takes the place of a wall that would otherwise enclose the fixed portion of the fixed portion. One or more adjustable portions are located adjacent, and attached to the one or more sides of the fixed portion of the base member. While in a partially or fully extended state, the adjustable portions have fully open or partially open bottoms that provide access for the pet to reach fresh grass underneath the cage or to conveniently clean bedding material.

摘要： The present invention is a pet cage having an upper cage member and a lower base member. The lower base member has a bottom that is partially cut out. An exchangeable plate or tray is provided and adapted to engage with the opening in the bottom of the lower base member. When an exchangeable plate or tray with access points, such as through-holes, are used, the pet can graze on fresh grass in a safe environment. When an exchangeable plate or tray without access points are used, the cage is restored to a conventional cage with closed bottom surface.
