Dealing with a diabetic cat can be a challenging experience for pet owners. Diabetes is a serious condition that can affect cats in various ways, including their overall health and life expectancy. One of the most pressing questions that pet owners have is about the diabetic cat lifespan and how long they can live without treatment. we will discuss the impact of untreated diabetes in cats and provide insight into how early diagnosis and management can significantly improve the quality and length of their lives. Diabetes mellitus in cats occurs when the body is unable to properly regulate blood sugar (glucose) levels. This is either due to the insulin resistance (where the body’s cells do not respond properly to insulin) or insulin deficiency (where the pancreas does not produce enough insulin). The lack of insulin leads to high blood sugar levels, which can result in a variety of symptoms and long-term health problems if not treated properly.
