Grumpy Cat and her permanent frown became a social media sensation after her picture was posted online in 2012.

Last year she won a $710,000 (£556,000) payout following a lawsuit against a coffee company that used her image beyond the limits of a contract they had signed with the cat's owners.

At the time, Grumpy Cat's lawyer David Jonelis, said he believed it was the first time an internet meme had won a court case.

The cat had 1.5 million followers on Twitter, more than 8 million followers on Facebook and 2.4 million on Instagram.

Her owner Tabatha Bundesen, of Morristown, Arizona, was even able to quit her job as a waitress, thanks to her pet's earnings, according to the Hollywood Reporter.

After Grumpy's death, the owners said: "Besides being our baby and a cherished member of the family, Grumpy Cat has helped millions of people smile all around the world - even when times were tough.

"Her spirit will continue to live on through her fans everywhere."

Wherever she is now, Grumpy Cat is probably still frowning.
