So I'm watching my sister's 2 rats and when she came to drop them off I had my boy Otis out and decided to let the 3 of them romp around the couch together. Otis and her rat Gus started rough housing and wrestling when all of a sudden they were both on their sides peeing on each other??? Like actively pee fighting. So much pee. Both my sister and I have never seen anything like it and I was curious if anyone else has?
