YEAH, I HAVE EXPERIENCED IT. IN FACT, IT WAS MY CAT. ONE NIGHT AFTER COMING HOME FROM MY DANCE CLASS, I HEARD MY DAD CUSS, AND THEN STOPPED THE CAR IN THE MIDDLE OF THE ROAD. I PICKED HER UP AND CARRIED HER HOME. IT ACTUALLY HAPPENED ON THE STREET BEHIND MY HOUSE. NOW WE LEARNED OUR LESSON AND USE INVISIBLE FENCE. IT REALLY WORKS. MAYBE ONCE OR TWICE THE CAT GETS A SHOCK, BUT THEN KNOWS REALLY WELL WHERE THE BOUNDARIES ARE. BUT I KNOW MY CAT IS OVER THE RAINBOW BRIDGE.............
