[Construction principles in the forepaw and hindpaw of the domestic cat (Felis catus). 1: Skeleton].
The differences in the skeleton of the forepaw and hindpaw of the domestic cat are an expression of a highly specialized, functional adaption: The mesaxonic forepaw with abducable first digit is used for running as well as for catching and climbing. The paraxonic hindpaw becomes, particularly through the arched construction of the metacarpus, a long and strong caulking tool both in sprinting and climbing up. The discussion focuses on evolutionary considerations. Moreover, common points and differences in the skeleton of the forepaw and hindpaw of the domestic cat and their importance are summarized and briefly compared with the situation in the dog.
