Honestly, if you’ve spent more than five minutes on the weird side of the internet lately, you’ve probably seen her. A small, green-blooded troll girl with a hat that looks like a cat’s head, framed perfectly by a digital speech bubble.
The Nepeta Leijon speech bubble is everywhere. It’s one of those memes that has somehow outlived its original source material by sheer force of personality. Or maybe it’s just because she’s adorable. Either way, Nepeta is a heavy hitter in the world of reaction images.
But where did this come from? If you aren't a veteran of the 2010s webcomic wars, the context might feel a bit murky. Let's fix that.
The Chaos Behind the Cat Girl
Nepeta Leijon comes from Homestuck, a massive, sprawling webcomic that basically ate the internet for a solid five years. Created by Andrew Hussie, the story featured a group of "trolls" from a planet called Alternia. Each troll had a specific gimmick. Nepeta’s gimmick was, well, everything cat-related.
She lived in a cave. She hunted beasts with her bare hands. She obsessed over "shipping" her friends into romantic pairings. Basically, she was the personification of the early 2010s Tumblr "fandom girl," but with actual claws and a body count.

The Nepeta Leijon speech bubble meme usually pulls from her specific typing quirk. In the comic, she didn't just talk; she purred. Every single line of her dialogue started with :33 <.
The "33" wasn't just a random number, either. It was a reference to the atomic number of arsenic (because her handle was arsenicCatnip) and a nod to the fact that her "Lusus"—her weird alien guardian—had two mouths.
Why the Speech Bubble Format Works
You've seen the format. It's a "reaction" image where a character is placed under a translucent or solid speech bubble, making it look like the person posting is actually the character speaking. It’s a way of saying "I’m with her" or "This is my vibe today."
For Nepeta, the speech bubble often contains her iconic cat puns. Words like "purr-haps," "feline," or "paw-sitively" are standard.

The reason it sticks? Contrast. Nepeta is canonically one of the most brutal hunters on her planet, yet she speaks in the most sugary, annoying cat-speak imaginable. Seeing a cute little cat-girl in a speech bubble saying something absolutely unhinged is the core of the humor.
How to Spot a "Real" Nepeta Post
If you're trying to use the Nepeta Leijon speech bubble correctly in the wild, there are a few rules. Hardcore fans will notice if you mess up the quirk.
- Lowercase only: Nepeta almost never uses capital letters. It’s too much effort when you’re busy shipping your friends.
- The Double E Rule: She replaces double "e" sounds with "33." So "sleepy" becomes "sl33py."
- The Prefix: You have to start with
:33 <. If you forget the space after the arrow, you’re doing it wrong.
It’s a specific brand of digital roleplay that has evolved into a shorthand for being "cringe but free." In 2026, we’ve moved past the era where being a fan of something was embarrassing. Now, posting a Nepeta speech bubble is a badge of honor for people who remember the "Old Internet."
The Enduring Legacy of :33
There is something genuinely fascinating about how a character who died halfway through a webcomic years ago is still a staple of social media.

Maybe it’s because Nepeta represents a specific kind of earnestness. She didn’t care that her "shipping wall" was weird. She didn't care that her friends thought her puns were grating. She just liked what she liked.
When people use the Nepeta Leijon speech bubble today, they aren't just posting a meme. They are tapping into that same energy. It's about being loud, being weird, and maybe being a little bit "paw-ful."
Your Next Steps for Nepeta Content
If you want to start using this meme or even create your own versions, here is how to get started without looking like a "newb."
- Find a high-quality sprite: Don't use a blurry screenshot. The original Homestuck sprites are pixelated, but they should be clean.
- Use a transparent speech bubble template: There are plenty of PNGs available that let you overlay the bubble on top of the character.
- Keep it authentic: Use her actual puns. If you’re stuck, look up a list of feline-related homophones.
- Embrace the :33: Don't be afraid of the quirk. The whole point is that it’s a bit much.
The internet is a weird place, but at least we have cat-trolls to help us navigate it. Whether you're a long-time fan or just someone who likes the aesthetic, the Nepeta speech bubble isn't going anywhere. It’s just too purr-fect to let go.
