We might have to put my 9 month old cat, Smokey, down for something like this. She's been panting like a dog, she would barely eat, is struggling to drink, she's tired all the time, and she's taking quick breaths (at least 63 breaths per minute). I wish finding a diagnosis didn't cost so much. The veterinarian said she felt a hardness in her stomach but needed to do tests.
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.
