What is National Internet Cat Day?
National Internet Cat Day is an annual observance held on 18 June, dedicated to the cats who have become global celebrities through the internet: the memes, the videos, the GIFs, and the social media accounts that have made felines the unofficial mascots of online culture. The day was founded by Kelly Wofford of LBK Wink in memory of her own internet cat, President Bill Clinton the Cat, who passed away on 18 June 2018. That date became the annual celebration in his honour. The day connects two genuine passions: the love of cats, and the internet’s extraordinary ability to turn that love into shared cultural moments on a global scale. For a broader look at feline appreciation online, you can also explore National Garfield the Cat Day on 19 June, which celebrates one of the most iconic fictional cats of all time.

The History of National Internet Cat Day
The story of internet cats begins well before the formal establishment of any awareness day. The relationship between cats and the internet is almost as old as the internet itself. By the mid-1990s, as email became mainstream, cat photos were already circulating among office workers looking for light relief. The arrival of broadband internet and YouTube in the mid-2000s transformed this quiet enthusiasm into something much larger.
The first cat video on YouTube is widely cited as “Pajamas and Nick Drake,” uploaded on 22 May 2005 by YouTube co-founder Steve Chen, featuring his cat Pajamas. By 2007, Keyboard Cat had arrived — originally filmed in 1984, the video of Fatso the cat appearing to play keyboard was uploaded to YouTube in June 2007 and became a defining early internet meme. In April 2011, Nyan Cat launched: an animated cat with a Pop-Tart body flying through space to a looping Japanese pop song, which went on to win a Webby Award for “Meme of the Year” in 2012. Grumpy Cat, born as Tardar Sauce, appeared on Reddit in 2012 and became a global phenomenon, spawning merchandise, a television film, and millions of memes.
By 2011, surveys suggested that cat content made up roughly 50 percent of all internet memes. The cultural weight of this was substantial enough to spawn CatCon Worldwide, a convention dedicated to cat culture, and Cats 24/7, a dedicated television channel. Various estimates put cat-related content among the most-watched video categories on YouTube, with billions of combined views across famous accounts and compilations.
National Internet Cat Day was established by Kelly Wofford, founder of LBK Wink, in memory of President Bill Clinton the Cat — her own beloved feline and, in her words, “the original Cyber-Feline.” When her cat died on 18 June 2018, she chose that date to mark the day annually, turning personal grief into a collective celebration of all the cats who bring joy through their online presence. The day pays tribute not just to famous meme cats, but to every owner who lovingly crafts content and shares their feline companion with the world.

Why National Internet Cat Day Matters
National Internet Cat Day is, on one level, a joyful excuse to celebrate something that already brings millions of people daily pleasure. But it also points to something more substantial: the way cats have become a genuine shared language of the internet, crossing cultural and linguistic barriers to deliver moments of unexpected connection. For many people, internet cats have been a source of comfort during difficult periods. The day also serves as a reminder of the real cats behind the content, encouraging support for animal welfare alongside the online fun. Whether you celebrate with a meme or a donation to a cat rescue, 18 June is a day worth marking. Much like Cat World Domination Day on 24 June — another feline-themed celebration close in the calendar — it’s a moment to acknowledge that cats, on the internet at least, have already won.
