In order to investigate the role of claws and pads in taking food the planter surface of the distal forelimb paw was recorded with a conventional video camera. The claws were involved in the great majority of trials. The morsel of food may be taken by piercing with one claw (rarely two) either alone or by pressure against a digital pad; support by pressure from another claw was also common, while pressure between two claws was used more rarely. Another technique was pressure between claws (without piercing) and digital pads. The morsel was also taken without participation of claws by pressure between digital pads and the central pad and more rarely between two digital pads.
