A 'redline' for
See? You don't even need 11 frames to make a good jump animation C:
The less frames, the faster the motion seems to be. Likewise, the more frames you have, the slower it will seem.
So, for a quick animal like a cat, less frames would work best.
Also, you can be the world's slowest jumper, doesn't necessarily mean you'll be stuck in the air longer than the rest of us
Hope this helps you make your kitty jump through that hoop-thing
PS: This is at 12 fps (frames per second)
