Keeping Up with the Kutest Kardashian: Mercy!Meet Kim's new kitten, whose aww-dorableness upstages the reality TV family

CAT WALK

Kardashian steps out in style with her purr-fect accessory: little Mercy! Making her debut Sunday outside the sister-operated Dash boutique in Miami, the cat could almost pass for another famous feline: designer Karl Lagerfeld's Choupette. "My new baby Mercy!" Kardashian writes of her kitten, whose moniker pays homage to boyfriend Kanye West's new single of the same name.
