The SCRATCH LOUNGE will last far longer than other scratchers because of the reversible super-dense honeycomb construction of the pads. The design is so unique, it was issued a U.S. utility patent! SCRATCH LOUNGE even prevents cats from damaging furniture! They enjoy the SCRATCH LOUNGE one hundred times longer than any conventional one-sided scratcher. That's more time on a SCRATCH LOUNGE and less time on your couch!
