Fidget spinners are supposed to help you focus, cat videos were invented to distract you. I combined the two, so they probably cancel each other out.
It's a small handheld version of a device from the 19th century called a zoetrope. The one in the pictures has a cat running as the animation, but it would work with any 12 frame animated picture.

This is a finished animated fidget spinner
Believe it or not, this is actually a pretty simple 3D modeling project
All it is is a drum with 12 slots in it evenly spaced, two identical wheels on the top and bottom with holes cut out to let light in, and a couple of caps and bearings.
I made a few different versions of animations to try out with the spinner
This one is a motion study of a cat done by Eadweard Muybridge in the 19th century. I saved each frame individually, brought the frames into illustrator, then placed them in the proper locations between the slots.
It's a simple design: two wheels, two bearings, two caps for your thumb and forefinger, and a drum with slits in it press-fit together
