It's exactly what you said. Bolt is a Disney film, not at anime.

Anime should be the contraction word for "Animation" basically, i think thats pretty obvious.
However, anime is understood as Japanese annimation that is characterized by fine drawing resembling that of Manga; big heads, big eyes(as i observed), and fine edge artistic style of presenting itself.
Honestly this is broad to discuss,.

Cartoons/Disney films DO NOT equal Anime. 'Nuff said.

In its standard use in English, "anime" is Japanese animation. And by "Japanese" I mean it was made by them, for them, and is thus regarded as somewhat foreign to most Westerners, even after it has been dubbed or otherwise released into the English market.

There are certain exceptions to the rule. Transformers, for example, was made by the Japanese but for an American audience (piloted by American moguls), so it would probably be classified as a cartoon. Golion was an anime later butchered by Americans, thus creating Voltron. Both are probably classified as anime, regardless (because they were originally intended for Japanese audiences.)

Hayao Miyazaki's work is mainly distributed by Disney, but it isn't Disney produced; thus, it is still anime in the purest sense of the word. Oban Star Racers was a joint Japanese-French venture, and hell you can label it however you want.
