It honestly depends on what kind of v-pet I'm running at the time. Watching movies, studying, drawing is something I do frequently and the Tama(s) aren't really involved. But running one that's demanding? That can be a little rough - I remember running a Yoda Giga Pet and it being so noisy it nearly ruined a viewing of a film or two, haha.
I don't associate running v-pets with any interests in particular, though.
