The cat next-door. Az's latest ginger mate (he seems to collect these). Not to be confused with the "evil ginger" who lives up the hill. I have made this mistake before and so Arthur is still getting used to the fact that I am not going to chase him off the premises.
Oh and the name.. Before we got introduced properly we called him Biscuit (because he is ginger), then we got told he was actually called Arthur so now he's Arthur Biscuit or "half a biscuit" (pronounced with a cockney accent).
