Grumpy cat's brother, so cute! He kind of has a similar mouth, just not as extreme. I think they should be characters in a book or cartoon series. Grumpy cat and his optimistic brother. :D <--- Grumpy Cat is a girl. Her real name is Tartar Sauce.
Grumpy cat has become more than just a sad or annoyed cat that we laugh at. The grumpy cat meme has become a rallying point for all of us who are tired of trying to be happy and want the sadness to envelope us like a warm hug of loneliness.
