If you're trying to decide what to complain about here, the salient fact is that the university settled.
As for the psychological benefits of carrying a rodent to school, I think about the young Keith Richards:
For companionship I kept pets. I had a cat and a mouse, Gladys. I would bring her to school and have a chat in the French lesson when it got boring. I'd feed her my dinner and lunch, and I'd come home with a pocketful of mouse shit. Mouse shit doesn't matter. It comes out in hardened pellets, there's no pong involved, it's not squidgy or anything like that. You just empty you pockets and out come these pellets. Gladys was true and trusted. She very rarely poked her head out of the pocket and exposed herself to instant death.
