for me personally. it is neither a turn on nor a turn off. People in general have things that peak curiosity and interest them its the way people are. If we go on the assumption that the animal in question isn't being physically harmed or forced who am I or anyone else to say its "wrong" or "sick". Before we all start casting stones remember that not to long ago same sex interactions were considered "sick" and "wrong". ANYWAY we are all kinky people in our own way right? so show some love for your fellow kinksters.
*HUGS* to all the kinky people!!!!
