Obesity is a significant health threat to cats, predisposing them to diabetes, joint disease, and respiratory complications. Prevention involves feeding a balanced diet, controlling food portions, and encouraging regular physical activity.

Cats can be susceptible to various viral and bacterial diseases, such as feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), and upper respiratory infections. Warning signs vary but can include fever, lethargy, appetite loss, and respiratory symptoms. Prevention includes vaccination, maintaining a clean environment, avoiding overcrowded conditions, and keeping cats indoors to prevent contact with infected animals.
