Hold the left mouse button while your cursor is on the cat to drag it around while doing what was said above. Click on different settings and tools to set Angle, Size, Whirl Effect, Ghost Effect, Color Effect as well as spawning and deleting clones. All clones obey the same settings and tools If it lags then make sure you're not in full screen mode because often, that's the problem. Of course the computer I work with is old and slow.
