In a Universe with Humans and Cat people, what would be different?

Maybe? Though I don’t think you’d see someone chasing them like normal cats. I think Timepiece Cats would probably just have a higher chance of ADHD and be more easily distracted. I could totally see a class of kindergartens totally losing focus on what’s on the board as their teacher is trying to point to things with their Laser pointer.

Catnip on the other hand would definitely have to be a controlled substance. With what it does to little cats, I wouldn’t want to find out what happened to big, people sized ones. Though humans would be still be able to purchase it in small amounts for pets. You’d basically just be ID’d then they’d give you a small amount.
