Pneumonia is an infectious/inflammatory disorder of the lung parenchyma. Tiny bronchi fill the lungs; each one ends in smaller sacs known as alveoli which contain tiny blood vessels. Oxygen is added to the blood and carbon dioxide removed via the alveoli. Pneumonia causes these alveoli to fill with pus and fluids which affect the lung’s ability to exchange gases. There are several causes including infection (viral, fungal, bacterial, parasitic), aspiration of gastric contents or medications.
Still, due to their characteristic nervousness, Russian Blue’s generally did not perform particularly well at shows, leading to a decline in their popularity into the 1980s. When breeders focused their attention on improving the personality of the breed through selective breeding, and by training their kittens to stay calm in a show environment, the Russian Blue once again became an attention getter and award winner. Since the 1990s the Russian Blue has been winning regional and national awards consistently, and today it enjoys a well-deserved and steady popularity.

The Russian blue is a sweet-tempered, loyal cat who will follow her owner everywhere, so don't be surprised if she greets you at the front door! While she has a tendency to attach to one pet parent in particular, she demonstrates affection with her whole family and demands it in return. It's said that Russian blues train their owners rather than the owners training them, a legend that's been proven true time and again.
