Do you consider them to be the same thing, or does one have features that the other does not?
For me, a cartoon is anything who's target audience is young children (Spongebob, Beyblade, Pokemon, etc.), while an anime is anything who's target audience is... well... anything else (Soul Eater, Naruto, Eureka 7, etc.)
Do you define them to be the same thing or completely different?
