<div class="container">Tardar Sauce (born April 4, 2012), better known by her Internet moniker "Grumpy Cat", is a cat and Internet celebrity known for her grumpy facial expression.
Her owner Tabatha Bundesen says that her permanently grumpy-looking face is due to feline dwarfism. Grumpy Cat's popularity originated from a picture posted to the social news website Reddit by Bundesen's brother Bryan on September 22, 2012. It was made into an image macro with grumpy captions.
