It seems polar bears are just as unfussed about stepping onto the scales as the rest of us.
Walker and Arktos lumbered up for their annual weigh-in at Highland Wildlife Park.
Both bears are still growing and weighed 70 stone (446 kg) and 73 stone (464 kg) respectively the last time they were weighed.
