Yes, Russian Blue cats can have health issues but are considered a healthy breed. Health issues they might face include:
Gingivitis: This is inflammation of the gums, which can lead to periodontal disease.
Heart conditions: Some Russian Blues might be susceptible to genetic heart conditions like hypertrophic cardiomyopathy (HCM), a heart condition characterized by the thickening of the heart muscles, which can affect the heart’s ability to function properly.
Obesity: Russian Blues have a hearty appetite and are prone to obesity. It is best to give them scheduled feeds and minimal treats.
