To the best of my knowledge of our current 3,300+ questions none ask about behavior seen in fictional animal characters. I also do not believe the topic of questions on pets about fictional animals has ever been discussed.
I don't believe that the community has decided if questions that would fall under the literature tag would be in or out of scope. This meta posts gives us place to discuss it.
Why now? My wife and I have been reading the audio book Watership Down and as we read it I realized how many questions it brought to mind the cross into the scope of pet house rabbits.

I am proposing that questions about fictional animal characters that otherwise relate to topics in scope at pets be included a in scope.
