Pythagoras thinks that he is superior to all other cats and most humans. He can cook, clean, take baths and do other human activities. He can understand, read and hypothetically write in English. His breed is Russian blue. He is very very rude and hates being called a cat. He uses very vulgar language.

His legal owner, aka roommate, is Daniel Kayaba who is a mathematics teacher and tends to be out of the house most of the time. Pythagoras is quite indifferent to Daniel. He is polydactyl.
