“Grumpy Cat”, aka Tartar Sauce (April 4, 2012-May 14, 2019)

Tardar Sauce, nicknamed Grumpy Cat, was an American Internet celebrity cat. She was known for her permanently "grumpy" facial appearance. She was the pet of Tabatha Bundesen.

While doing some research on her, I had no idea that she died not too long ago. Or that she had her picture taken by the late Stan Lee.
