It's Game day, and athletes Troy Paw-Lamalau, Feline Manning and Tomcat Brady are on the field. Napping. Players as cute as those competing in the Hallmark Channel's first Kitten Bowl (Sunday, Feb. 2, noon/11 a.m. c) can get away with anything, even using a time-out to climb up cohost Beth Stern for a cuddle. In fact, that sort of behavior is encouraged. Just ask the animal activist (and wife of Howard Stern), whose latest project is raising funds for Bianca's Furry Friends, a planned 14,000-square-foot state-of-the-art Feline Adoption and Wellness Center at New York's North Shore Animal League America.
