Why does Kaeloo put so much emphasis on the game not being violent? In the previous episode, she got into trouble with her friends for using excessive violence on Mr. Cat, and he rejected her apology when she tried to apologize to him, so she's trying to prevent a similar incident from happening.
Fridge Horror
The mere fact that Kaeloo thinks that her forcing a kiss on a clearly unwilling Mr. Cat was okay because it wasn't physical violence, and ignores the fact that he is clearly traumatized afterwards while continuing to flirt with him.
The Forceful Kiss was offscreen and there's no indication of how much time passed between that scene and the next. Given the kind of show this is, it's quite possible Kaeloo did a lot more than just kissing Mr. Cat...
