Cat is the native language of Cat Demons, and as such, Shiro is fluent in it.

It is mostly variations on the word "Meow," but as Shiro has noted "Meow has many interpretations, depending on volume, length, tone of voice..." which cannot accurately be conveyed over a text-based medium. And you wondered why you'd never read any great cat novels. That's why.

Numerous attempts have been made by Ed in the chatroom to speak cat, only resulting in either insulting himself or Shiro. Shiro advises him to stop trying, but his attempts continue. Damn child prodigies.

Recent attempts have included:

• "Meow Meooooow Meow Meow Meow Meooooow..." - ...this can't really be repeated, as the wiki will buckle under the filth described by Ed, relating to his brother. Seriously. Don't ask about it.
• "Mrrow." - "Do me now, please."
• "Meow Meow Meooooow Meooooow" - "I want to lick whipped cream off your mom."

EDIT: ALL TRANSLATIONS ARE DONE BY SHIRO. NO ONE KNOWS IF IT'S TRUE, LEAST OF ALL THE LAST ONE.

EDIT THE SECOND: Who are you gonna believe, the kid, or the one who actually speaks it?

EDIT THE THIRD: And also it should be noted that Ed didn't mean anything by the meows, except to annoy Shiro. He doesn't even know the language exists, Allendamnit.

EDIT THE FOURTH: He did know. Shiro kept telling him not to speak in a language he didn't know. BUT HE KEPT GOING. HE JUST KEPT GOING. Even Allen won't save someone that foolish, bwahah.

EDIT THE LAST: The attempts are apparently in chronological order. It should be noted that Ed did not know Cat existed at the point of the first comment, figured the second comment shouldn't mean anything since it's too short, and asked the third only out of curiousity.

EDIT THE ACTUAL LAST: They are not. The last one was actually said first, and actually started the whole thing. So there~

EDIT THE ACTUAL ACTUAL LAST: They are in chronological order now.

I LAUGH AT YOUR ATTEMPT TO STOP THE EDITS: Cats don't have much to talk about besides sex anyway.

EDITING FOR MY REAL CAT: And food. Mine are very vocal about their food.

NINJA EDIT: Are you sure about that? My cat flirts with all the others in the area...

OTHELLO EDIT: ...and Shiro wonders why cats don't yet rule Hell.

SHIRO EDIT: Oh come on, Hell'd be like, loads better if food and sex was the primry concern instead of war and politics. Tell me I'm wrong.

AZIRAPHALE EDIT: I thought they had plenty of those, too. Lust and Gluttony, after all.

SHIRO'S REPLY TO AZIRAPHALE EDIT: You're obviously talking about the fun hell.

OTHELLO EDIT THE SECOND: Are you trying to tell me that our Hell isn't fun? :D

SHIRO'S REPLY TO OTHELLO: No, it's a barrel of laughs. I mean, the number of times I've nearly been killed is an utter JOY.

TYR'S EDIT: MREOOOOOOOOOOOOOOOOOOOOOOWL!!

SHIRO EDIT: Well, I think we can now safely say this is the filthiest page on the wiki. Good job, Tyr.
