'Some days are grumpier than others.' Grumpy Cat dies

The internet sensation Grumpy Cat has died.
The cat's real name was Tardar Sauce, but she gained internet fame and was even the star of a movie – thanks to her permanent scowl.
Grumpy Cat's owners posted on Instagram that she died due to complications from a urinary tract infection.
The cat was 7 years old.
Her owner says that her grumpy-looking face is due to feline dwarfism and the placement of her teeth in her mouth.
