Which scratcher suits my cat?
Watch where they scratch
Up the sofa back or door frame: a vertical sisal post. Along the rug: a flat cardboard pad. Both: the L-shaped board.
Size matters
Large breeds need the 32-inch posts and the thick 5.5-inch column; kittens are happy with any pad.
Climbers
Cats that live on top of the fridge want the 80-inch wall tree.
