It is a known fact that cats listen to no one. It's not that they don't understand. Cats are incredibly smart. They know what we want (and don't want) them to do. It's just that they do not care. Cats are independent (until they get their precious claw stuck in something they weren't supposed to touch and start crying), cats can take care of themselves (and if you don't give them their meal on time, they will tell you off about it), cats go where they want, do what they want, and live their lives to the fullest. And that's definitely the case with this cat.
This cat is a purrfessional. He has found his way into a university full of students and has decided to become one of them. He has a schedule, goes to classes, has a lunchtime set in a specific room, uses the elevator. He knows what he's doing. He's enjoying his new and improved life, and we're enjoying watching it.
