Beth Ostrosky Stern, wife of radio host Howard Stern, and John Sterling, the voice of the New York Yankees, will co-host "Kitten Bowl," the Hallmark Channel's feline answer to Animal Planet's venerable "Puppy Bowl" specials that air on Super Bowl Sunday. The Hallmark Channel yesterday said the program -- produced in association with the Port Washington-based no-kill shelter North Shore Animal League America, with which Stern has long been involved -- will air Feb. 2, from noon to 9 p.m.
