A Cat. In A Hat. On A Bike
This is a cat in a hat on a bike. No CGI, no tricks, no stunts, just some guy on bicycle who apparently loves his cat enough to install some handlebars and make sure his kitty has some shade.
That is one very awesome and well-trained cat. It's obviously not happy to be on the bicycle, but at the same time, it doesn't leap off and run away, which it could easily do. As it seems to have all its limbs it fortunately doesn't seem to have learned not to jump into traffic the hard way.
As for the hat, we're assuming that's a custom job. Either that or somebody has a small but thriving business in selling hats for cats. Maybe he got it from Etsy?
