With an 18-year run on Broadway that contributed a reported $3.12 billion to New York City’s economy, Andrew Lloyd Webber’s Cats proved that tourist dollars could keep a musical afloat — even one with special needs totaling 1.8 million pounds of dry ice and 3,247 pounds of yak hair. Based on T.S. Eliot’s Old Possum’s Book of Practical Cats — a slim collection of ’30s-era poems about alley cats — Cats debuted in London in 1981, landed on Broadway in 1982, and scooped up seven Tonys including Best Musical in 1983. Though it closed in London after 3,358 performances and in New York after 7,485, the mega-musical still has its claws in the title of “the longest continuously touring show in American theater history.” Jonathan Pennington and Jovi Lee Gonzalez co-direct at the Cameo. $15-$33; 3:30pm Sun, Dec 23; The Cameo Theatre, 1123 E Commerce, (210) 212-5454, cameocenter.com.
