It's been a busy year for Grumpy Cat, and the holidays are no different. The frowning kitty is now starring in a brand new Christmas music video.
Grumpy Cat, along with fellow Internet cats Colonel Meow, Oskar the Blind Cat, Nala Cat and Hamilton the Hipster Cat, have formed a superstar feline group to sing "It's Hard to Be a Cat at Christmas."

The video also serves a good cause: For every view, up to the first 500,000, Friskies donated one can of wet cat food to shelter and rescue organizations across the country.
