Feline diseases refer to various health issues that can affect cats, impacting their overall well-being. Common diseases include feline leukemia virus (FeLV), which weakens the immune system, and feline immunodeficiency virus (FIV), which can lead to serious infections. Other conditions, such as chronic kidney disease and diabetes mellitus, are also prevalent among cats, especially as they age. Preventative care, including regular veterinary check-ups and vaccinations, is essential for maintaining a cat's health. Early detection of symptoms, such as changes in appetite or behavior, can help in managing these diseases effectively. Proper nutrition and a safe environment also play crucial roles in preventing feline diseases.
