Persuading polar bears Walker and Arktos onto the scales

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.
