Abstract: An expandable hay feeder, comprises a stretchable, resilient grid attached to a frame. The frame is secured to a wall or surface by a pair of hinges on one side and a latch on the other so that the frame can be unlatched and rotated away from the surface for adding hay. The hay is held between the wall or surface and the stretched grid in such a way that an animal can feed through the holes defined by the grid. The cords of the grid are made of rubber cores covered with abrasion-resistant fabric. "S" hooks hold the grid to the frame. A surface is provided in an alternate embodiment for opposing the stretched grid when the device is to be mounted to a fence or other open surface.
