Finally, the perfect cat for all those physics problems!

If you took early undergrad-level physics, you probably remember that many of these problems included necessary simplifications, including massless, frictionless pulleys and massless ropes that didn’t stretch. I now present to you a real-world version of one of those simplifications: The spherical cat!
