I know right?
Why would you do that to me?
You're a sick human being.
Sick!

Sick!
The real question is: Does Avatar the Last Airbender count?
I have a feeling you're joking...
...
But I don't care!
Depends on how you define "anime."
Ask a Japanese person if it's anime and they'll say it is.
But they'd say that any cartoon is "anime."
Songebob is anime.
Is "anime" an artsyle? If that's your way, then you could make a case for Avatar since the creators have admitted to, and made it very clear through their style, that there is Japanese influence. Though it's arguable even under that definition.
And you could then also argue that cartoons made in Japan aren't anime, since not every cartoon from Japan "looks" like "anime."
I, and most people, prefer to define "anime" as "cartoons of Japanese origin." In which case Avatar is not an anime.
