A first-in-first-out microelectromechanical memory apparatus is disclosed. Such proposed flooring can withstand frequent traffic of heavy animals while ensuring a high degree of animal safety and problem-free mobility. The hot melt adhesive can cure by exposure to moisture or harden by cooling, or a combination thereof. Screws are driven through the wall panels, through the elastomeric strips, into the studs to fasten the wall panels to the studs.
