LAW TO REPORT HITTING OR INJURING A CAT WITH A MOTOR VEHICLE ON UK ROADS

At the moment there is no laws about reporting hitting a cat on the uk roads and i believe there should be. As a cat owner i know how it feels to lose a cat thats been hit by a car and with so many cats being found on the uk roads and the owners not knowing i believe its about time there was a law that says if you knowing hit a cat you must report it to the police,rspca or a local vet so that the owners can be reunited with they pet.
