Abstract: Flooring for an animal shelter uses inwardly sloping wedge shaped flooring members held in a spaced apart parallel relationship by wedge shaped center spacers and end spacers having an outward slope. These wedge shapes match such that when the inclined surfaces of the spacers and the flooring members adjoin each other the flooring members will hold the spacers in place. The flooring members ends also incline inward so that a pair of aligned flooring members with their ends abutting enclose a triangular shaped space. A rod extending through the inclined surfaces of the center spacer is arranged to extend into this space when the inclined surfaces of the center spacer and the two flooring member adjoin. This rod prevents the center spacer from moving longitudinally along the flooring members. An end spacer with similar inclined sides has a bar extending across an end perpendicular to the inclined sides.
