She did not say how much the cat earned.
The cat from Arizona had "helped millions of people smile".
The famous and adorable cat, who was only seven, sadly on Tuesday 14 May "at home in the arms of her mommy, Tabatha".
Owner Tabatha Bundesen founded Grumpy Cat Limited, and the cat made numerous appearances, including commercials.
The internet star now has millions of followers on social media.
The owner's brother, Bryan Bundesen, made the cat famous by taking her photo and posting it on Reddit on September 22, 2012, when the cat was only five months old. The company had a licensing deal to sell iced coffees called "Grumpy Cat Grumppuccino", but then added a line of "Grumpy Cat Roasted Coffee" without permission.
"It was suggested that the original photo was Photoshopped, so we posted a few videos on YouTube", the owners said on the official Grumpy Cat website. It was the following year that she landed her own Lifetime movie, Grumpy Cat's Worst Christmas Ever, featuring the voice of Aubrey Plaza as the title character.
Last year, USA coffee company Grenade was ordered to pay the Bundesens $710,000 for exceeding an agreement to use her image. The family didn't breed Grumpy Cat so unfortunately, her lineage ended with her.
"Quite rightly, Grumpy turned up and upstaged all of the Jellicle cats", Imogen said.
