Let's see...
Whisker's creator, Dr. Casius, lives in a very, very strict society, which he has worked hard in to get to the high ranking spot Dr. Casius is in now. When an experiment goes wrong, resulting in a three and a half foot tall rat with an IQ of 186, Dr. Casius has to find a way to keep Whiskers a secret while keeping Whiskers' growing curiosity at bay. Naturally, things go wrong, and that's where the plot really picks up.
