This is a promotional video for a popular game in Japan that features cute, little cat people whose faces are on these cat hats. You don't need to understand the context to understand how cute these videos are. Fortunately, there's a lot more where this video came from.
Bubba lives near Leland High School in San Jose, California and he loves going to school. Every day he'll venture out, get treats from his favorite teachers and hang out with friends until the school day is over and everyone has gone home. He started by following his owner Matthew to the nearby Bret Harte Middle School and graduated to Leland High School with him. He has since dedicated himself to getting a good education.
