Nebelung

Nebelungs are mild, soft-spoken, and gentle. They are generally reserved around strangers, ranging from hiding-under-the-bed timid to warily eyeing intruders from a safe distance. Given humans' unpredictable behavior, this could be interpreted as a sign of extreme intelligence.

To their family, Nebelungs are like Russian Blues, affectionate and playful although not intrusive. They tend to bond with a select few humans and stay loving and devoted throughout their lives.
