The video was posted to YouTube yesterday - MJ's first birthday, as it happens.

Salida, a bike courier in Philly, has trained MJ to sit on his shoulder while he delivers parcels through the city.

"MJ (short for Mary Jane) enjoys the wind rushing through her fur and she moves around from shoulder to shoulder," he told the Daily Telegraph Australia back in October.
