When he first arrived in Las Vegas, Russian-trained juggler and clown Gregory Popovich incorporated his pet cat Snowbird into his act by chance, to overwhelming audience response. Inspired to expand the furry cast, Popovich headed to a local shelter where he was appalled at the number of abandoned pets. Now touring nationally with stops at Late Show with David Letterman and America?s Got Talent, Popovich leads a four-legged cast of 15 cats and 10 dogs, all former strays before becoming stars and, in some cases, internationally ranked poker players. Pups propel scooters across the stage and double-dutch jump rope as cats shimmy over parallel bars. European-style clowns and mesmerizing jugglers complement bouts of barking and meowing. And this season, the Pet Theater welcomes a new duo into the fold? a miniature horse and goat?who are certain to win audiences' hearts with their hoofed camaraderie and braying banter.
