Yeah, sorry I didnt get to this earlier. What you may want to do is to keep an unsmoothed version of your model underneath the smoothed one. Then, you assign a transparent material to the unsmoothed one. You also assign the fur to the unsmoothed one.
that way the smoothed one looks like it has fur, but it doesnt.
Another thing you could do is to apply the fur directly onto the smoothed one.
