own business when a neighbor s guard dog appeared out of nowhere. the home security cameras rolling as dog grabbed boy and cat came to the rescue. that s right, cat. watch closely. that black flash on the right side of the frame is jeremy s kitty cat pouncing on the pooch, chasing him off. saving little jeremy. until you looked at the videotape you didn t know the cat was involved. no. we both gasped and were like holy cow. reporter: the cat adopted the couple five years ago, following them home from the park one day. when jeremy was a newborn she would climb into his crib and curl up besides him. an unusual bond for a creature by nature tends to be fairly aloof. to have her with no regard for her own life fly at the dog to protect him. i ve never seen anything like that. this is round one, round one to the kitty cat, huh?
