LONGCAT_
The infinitely long cat of 2006 — fullscreen, in your browser. LONGCAT IS LOOOONG.
What is this?
LONGCAT IS LOOOONG. This is Longcat — the 2006 meme of a white cat (named Shiroi) held up by its forelegs until its body looks impossibly stretched — recreated as a fullscreen browser screensaver. The cat sways gently like a pendulum, blinks, and stretches as far down the screen as you like. Drag the stretch slider to make it truly endless.
⚠ A harmless fan tribute — it's just a web page, nothing is installed. The cat is hand-drawn, not the original photo. Press Esc to leave fullscreen.
The lore
Longcat became one of the defining absurdist memes of the mid-2000s. Endless Photoshop battles stretched the cat across continents, into orbit, and beyond. Fans invented a mock prophecy in which Longcat (good) battles its inverted black-furred rival Tacgnol (evil) for the fate of the universe. The whole joke rests on three words: longcat is long.

▸ Frequently Asked Questions
FAQ — Longcat
What is Longcat?
Longcat is a 2006 internet meme built from a photo of a white cat (named Shiroi) held up under its forelegs so its body appears impossibly stretched. The caption "LONGCAT IS LOOOONG" and endless Photoshop battles made it one of the defining absurdist memes of the mid-2000s 4chan era. This is that cat recreated as an animated browser screensaver.
Is this the original photo?
No. The original meme used a photograph. This is a hand-drawn cartoon tribute rendered with HTML5 canvas and JavaScript so the cat can sway, blink and stretch, with nothing to download or install.
Who is Tacgnol?
Tacgnol ("Longcat" reversed) is Longcat's black-furred rival — an inverted-colour version of the cat that fans cast as the antagonist in a mock cosmic prophecy of good versus evil. It became a running joke alongside Longcat.
How do I make it fullscreen?
Click anywhere on the cat or press Enter Fullscreen. It fills the whole display. Move the mouse to show the exit button, or press Escape to leave.
What can I customise?
Use the stretch slider to make Longcat as loooong as you like (even off the bottom of the screen), adjust how much it sways, change the caption, pick the background colour, and toggle the Impact caption, the holding hands and the scanlines.
Is it free?
Yes, completely free. No account, no ads, no watermark. It's one of the free browser-based tools at jasperbernaers.com.
