This paper describes a three phase project concerning the watchin, analyzing, and describing of motions of a cat in various gaits. All data is based on two 16mm films of an actual cat moving on a treadmill. In phase I, the low level issues of tracking key points on the cat from frame to frame are discussed. Phase II deals with building and using a graphics tool to analyze the data of phase I. Pahse III is a high level discussion of cat locomotion based on the trajectories and movements explored by phase II.
