The internet loves a good animal meme, but none have taken the web by storm quite like Grumpy Cat.
After the displeased feline's facial expression went viral, the owners were quick to capitalise and make some serious money with successful merchandise lines.
One such product was the "Grumppuccino" iced coffee from Grenade Beverage.
According to TorrentFreak, the Californian company licensed the copyright and trademarks to sell the product, but things went sour after it started selling other "Grumpy Cat" branded products.
