The claws are out. Klaw Mark Kittens in Lansing, Michigan, and Wildcatz in Nottingham, England, are performing different kinds of semi-sophisticated and choreographed "catfighting," involving kitten costumes and loads of eye scratching. "We call it vintage burlesque wrestling," troupeleader of Klaw Mark Kitttens Autumn Luciano said. Though she said, "It's mostly theater," Luciano didn't sugarcoat it. "When showtime comes, the girls will kick each other's butts."
