An anthropomorphic comic?

Question

I'm looking for an anthropomorphic comic where most of the characters were in college. It included a mean professor (which was a goat or a ram). It also had a mysterious character who played an instrument ( I don't remember what it was).I can also remember an amusment park.

Just remembered a little more. One part a girl (mouse) was cleaning the mean professor's(goat or ram) house. And another guy,which was living there, went crazy, I think he was a cat..
