The present invention relates to a prefabricated plaything for a pet. More specifically, the present invention provides an amenity that a pet can easily ascend and descend, including: an easily replaceable friction means and a shelter, wherein the pet relieves stress and trains its body while rubbing its body, claws, and teeth against the friction means or biting the same, and rests in the pouch of the shelter in which a darkroom comfortable for resting is maintained. A technical means for achieving this comprises: a base panel that has a column formed on the upper surface thereof, wherein the column has a fastening hole an extension rod that has a fastening protrusion formed on the lower portion thereof, which is screw-coupled to the fastening hole of the column, and a coupling hole formed in the upper portion thereof a friction rope positioned to surround the outer surface of the extension rod and a stem part that has a coupling protrusion formed on the lower portion thereof, which is screw-coupled to the coupling hole of the extension rod, and is provided with leaves.
