It took me a several tries before I got the ears right. But every-time, after rendering with the particle system attached to the object, the hairs on the ears started to look weird.
I tried to flip the Normals, give the object the right Scale before joining the ears to the body. Also tried several different starting Objects for constructing the ears.
I noticed that the Normal spread was different on the ears part of the object, comparing to the rest of the object, when they where joined together. Than it hit me. For me the problem lies in the fact that the complete body was modeled from Metaballs, only for the ears I used a UV-Sphere. I don’t know why I did that.
I guess it’s important using the same kind of Mesh or Metaball to construct an object when applying a particle system on it.
First the version with the weird ears:
The version with normal ears:
