What’s the difference between a Russian Blue and Nebelung?

The primary difference between a Russian Blue and a Nebelung lies in their coat length and texture. The Russian Blue has a short, dense, and plush coat, while the Nebelung has a medium to long, silky coat with a distinct undercoat. This gives the Nebelung a more flowing and luxurious appearance compared to the sleek, smooth look of the Russian Blue. The breeds are so similar in appearance that some consider the Nebelung to be a long-haired variety of a Russian Blue. However, most registries recognize them as a separate breed since Russian Blues only make up part of their lineage.
