International Cat Day: felines take over the internet (even more than usual)

Cat lovers around the world rejoice! Saturday is #InternationalCatDay - the day when moggies rule the internet (even more than usual).

Celebrated on August 8, International Cat Day was created by the International Fund for Animal Welfare in 2002.

In the decade since, the world's most famous cats have acheived international fame on many fronts, including fashion and their ability to sleep in weird places.

The most revered internet kitty of all, Grumpy Cat - real name Tardar Sauce - has amassed millions of fans around the world.

And the Internet Cat Video Festival, which will be held on August 12 this year, attracts thousands. Voting is now open for the People's Choice Award.
