Sure, I'll watch a traditional Disney cartoon on occasion, nothing odd about that.
Then of course there's Futurama, Family Guy, Simpsons, South Park etc., not to mention a whole slew of animé series, all of which are animated (and could be termed cartoons), and many of which are specifically targeted at adults. Depending on your definition of "cartoon" it needn't be contrary to having an intended adult audience.
And many cartoons aimed primarily at children even encompass some layers for adults as well, sometimes entire thematics Pixar style, sometimes something a bit less elegant [http://www.youtube.com/watch?v=FUJOAaxqc0U&feature=related]. Not that it's any requirement to enjoy them at any age if you feel like it though.
