发明名称 Birdcage perch
摘要 A lightweight perch formed from plastic, wood or the like, has an outer surface on which is applied a granular material such as sand or the like. A thin layer of adhesive or solvent may be used to attach the granular material to the perch. The resultant perch duplicates the healthy, stimulative effects of expensive concrete and sand perches at a tremendously reduced weight and cost.
