Maybe it's the furry costumes. Perhaps it's "Memory," which has been recorded by more than 150 artists. It's possible we even subconsciously wish our own felines had such exciting lives. Whatever the reason, there's no arguing Andrew Lloyd Weber's legendary Cats has captured our imaginations. The longest continuously touring show in U.S. history arrives at PlayhouseSquare's Palace Theatre Jan. 21-23 and will be here a hair longer than the one-night-a-year Jellicle Ball around which Cats' plot revolves. Grab a seat. We promise they won't scratch.
