John and interested others:

How about Megamurine? or Maximurine?

I must agree with the shameful discrimnation rats have endured throughout
history. After all, they are not the only reserviors for bubonic plague but
they alone carry the stigma. I dare say, our Supreme Court (US) would
probably agree with your Court and "murine" would stand here as well. More's
the pity.
