Caturday is the internet tradition of posting cat images and LOLcat memes on Saturdays, originating from 4chan's /b/ board around 2005[1]. The name combines "cat" and "Saturday."

Where did Caturday come from?

The tradition grew on 4chan's /b/ board[1], with a LiveJournal community forming in February 2006[3] and I Can Has Cheezburger popularizing the concept when it launched in 2007[2].

What does Caturday mean?

It's a portmanteau of "cat" and "Saturday," designating Saturday as a day to celebrate cats online by posting photos, memes, and LOLcat image macros[1].

How do you use Caturday?

Post a cat photo or LOLcat meme with the hashtag #Caturday on social media, traditionally on Saturdays[1]. Classic posts include lolspeak captions, but modern posts are typically just cat photos[2].

Is Caturday still popular?

As of 2021, the hashtag #Caturday was trending on Twitter most Saturdays[1]. I Can Has Cheezburger, the site most closely associated with LOLcat culture, still publishes daily cat content[9].

Lolspeak is the intentionally misspelled, grammatically creative captioning style used in LOLcat images and Caturday posts[2]. It blends baby talk with internet slang, producing phrases like "I CAN HAS CHEEZBURGER?" and "IM IN UR NOUN, VERB-ING UR RELATED NOUN."

What is the connection between Caturday and I Can Has Cheezburger?

I Can Has Cheezburger launched in January 2007 and built directly on the Caturday tradition by posting LOLcats every day rather than just Saturdays[2]. The site became one of the most popular humor destinations on the web.

Who created Caturday?

No single creator is credited. The tradition grew organically on 4chan's /b/ board[1], and the concept spread through independent communities including a LiveJournal group in 2006[3] and a dedicated Tumblr in 2009[7].

When did Caturday start?

The tradition dates to approximately 2005-2006[2]. Urban Dictionary's first definition appeared in October 2006[6], and a LiveJournal community was already active by February 2006[3].

How far back does the tradition of funny cat photos go?

Photographer Harry Whittier Frees created staged kitten photos with humorous captions in the early 1900s[2]. Caturday brought this century-old tradition into the digital age.

What happened to lolspeak?

Lolspeak was a defining feature of early Caturday and LOLcat posts but largely faded from mainstream use through the 2010s[1]. Modern #Caturday posts typically feature plain cat photos without captioned text.

Is there an official Caturday website?

Metro News notes that Caturday has its own official website[1]. A dedicated Caturday Tumblr blog was also active, describing itself as "probably the best cat blog in the world"[7].

Also known as: Caturday Meme

Caturday is the internet tradition of posting cat images and LOLcat memes every Saturday. The practice started on 4chan's /b/ board around 2005, spread through communities like LiveJournal and I Can Has Cheezburger, and turned into a weekly internet ritual still observed across social media. The hashtag #Caturday trends on Twitter most weekends, with users sharing photos and memes of their cats1.

Overview

Caturday is a weekly ritual where users flood image boards, blogs, and social feeds with photos of cats on Saturdays3. The format ranges from plain snapshots of house cats to LOLcat image macros with broken-English captions layered on top. Anonymous posters on 4chan's /b/ board treated the day as an unofficial holiday, badgering the board to 'post some fucking cats'2.

By October 2011 the LiveJournal Caturday community had grown to around 2,196 members swapping macros and pet photos on a set schedule3. Cheezburger properties, Tumblr, and Twitter later folded the same idea into their tagging systems, so a Saturday scroll through #caturday brought a fresh wave of cat content on any given week3.

Tracing the exact birth of Caturday involves multiple threads. The domain "caturday.com" was registered on April 30, 2005, and Time magazine's Lev Grossman placed the concept's roots in early that year after reader feedback corrected his initial estimate5. One of the first non-4chan uses of the name was a Blogspot blog called "Caturday" created November 16, 2005, by a New Hampshire user named Sharyn who posted stories and photos of her own cats rather than LOLcat macros4.

The meme tradition itself, posting LOLcat image macros on Saturdays, took root on 4chan's /b/ board1. A LiveJournal community launched on February 5, 2006, with the rallying cry "Post some fucking cats!"3. Urban Dictionary's first definition appeared on October 24, 20066, and one of the earliest archived Caturday threads on 4chan dates to December 12 of that year4.

How It Spread

I Can Has Cheezburger launched in early 2007 and blew open the doors for LOLcat culture, posting cat content daily rather than just on Saturdays2. The site's first Caturday-tagged image went up on January 13, 2007, two days after launch4. That same year, the trend appeared on MetaFilter, Fark, and in the University of Pennsylvania's student newspaper8. By mid-2007, search interest for the term hit its all-time peak.

A Caturday Tumblr blog appeared on June 1, 2009, billing itself as "probably the best cat blog in the world"7. Through the 2010s, #Caturday became a regular trending hashtag on Twitter1. By 2021, Metro News reported it was trending most Saturdays, with users sharing cat photos to an audience well beyond 4chan's original community1.

How to Use This Meme

The common convention is simple: on any Saturday, post a cat. That typically means a snapshot of your own cat, a favorite LOLcat image macro, or a repost from an older 4chan or Cheezburger thread. On Tumblr and Twitter, the post often includes the #caturday tag so it lands in the running Saturday feed alongside everyone else's cats3.
