"This is the most amazing and ingenious scratcher ever devised for a cat! I have been through them all: the posts with carpet on them, the sisal door-hangers, the kitty-condos, even the "scratch here" sprays and anti-scratch here sprays, and NOTHING tops these inexpensive, clever little Alpine scratchers! My cats LOVE them and they haven't touched my furniture since!
One caution, though! Beware of "generic" refills! I bought a pair one time and the cardboard was horribly dusty, coated in some kind of stiffener gunk that irritated my cat's paws, and came with non-Cosmic catnip (a stingy little packet of something herbal that had no smell.) Only buy the refills if they have the genuine Cosmic Catnip packet in them!"
