WEST MILFORD, N.J. -- At least one bear doesn't want to know Jack. Jack is a 10-year-old orange-and-white tabby in West Milford, N.J. And when the cat spotted the bear in a neighbor's yard earlier this week, the clawless kitty let the bear know who's boss. The bear scurried up a tree and eyed the cat for 10 to 15 minutes, while Jack stared and hissed from the ground. The bruin inched its way down before jumping off and running away. But Jack chased the bear into the brush and up another tree. That's when Jack's owner realized what was happening and called her cat. The bear took off as Jack rubbed up against its owner and the neighbors. Jack's owner, Donna Dickey, told The Star-Ledger of Newark Jack considers the area his turf and doesn't want anyone in his yard.
