This noon I noticed one of wall posts by Dunia Kucing about a cat name Macavity who always takes a ride on bus couple of times per week in Walsall, England. Macavity rides the bus by its own and always jump off at the same stop. Since then, the cat known as Macavity the Mystery Cat. For full story of this cat you can read it here and guess what he's on the wikipedia too ahahaha (link).
I also found another story of bus riding cat name Casper (link) however he died after hit by a motorcycle (link)
