I did some analysis on the best of the footage that I got of the tiger at Noah's Ark Farm, looking at the way that the legs move and the way that the head bobs.
The legs seemed to move in something of a pendulum motion, with the front paw remaining nearly in place until the back paw had started to catch up with it, giving it the impression of that desk toy with the balls that demonstrate conservation of momentum.
The legs on one side also appear to stop moving when the legs on the other side are in motion. In higher speed motion, of course, all of the legs are in motion at once, but as you can see here, this is more of a slow pr
The head also bobs when the tiger is in motion, rising and falling as the weight shifts, with the front paws appearing to be the determining factor in relation to the timing of the rises and falls.
Extra analysis on the tail is in my sketchpad.
