Grumpy Cat dies aged seven: 'Some days are grumpier than others'

Internet's No 1 cat, with a face that launched a thousand gifs, expires in Arizona

The greatest frown in town: Grumpy Cat - a life in pictures

Grumpy Cat - the most famous cat on the internet, whose downturned mouth and unimpressed expression was the universal digital shorthand for displeasure - has died.

The seven-year-old cat, real name Tardar Sauce or Tard, became one of the internet's first "petfluencers" after gaining fame online for her perpetually gloomy gaze, launching an empire worth millions. She died in the arms of her owner, Tabatha Bundesen, in Phoenix, Arizona, on Tuesday morning after complications from a urinary tract infection.
