We’ve covered the cat-loving cyclist Rudi Saldia and his fearless feline, MJ, before, but the twosome are now stars of GoPro’s newest commercial, featuring them cruising around the streets of Philadelphia being filmed by GoPro’s cameras.  Saldia and MJ took Youtube by storm with their videos of MJ riding on Saldia’s back with the city whirling by.  My cat would never put up with such shenanigans from me, but Saldia and MJ obviously have an amazing bond.
