This hilarious video shows the moment two rats squared up to each other and had a 'boxing match' in a kitchen cupboard. The clip shows the rodent grappling, tossing each other side to side and rolling around in a cartoon-style fight. But then one drags the other across the shelf before they bizarrely both rise up on their back legs - and slap and strangle each other with their forelegs. One gets the upperpaw by jumping on to a higher shelf and taking aim from there.
