The four "silent" killers in cats.

3. Diabetes mellitus

Another precious and silent killer that affects cats is diabetes mellitus. Since many of our cats are often overweight or obese, they are at greater risk of contracting the disease. In diabetes, the pancreas is unable to isolate enough insulin (type I diabetes) or insulin resistance (type II diabetes). Insulin is a natural hormone that causes sugar (ie, sugar in the blood) in the cells. Due to the lack of glucose in the cells, the body produces more and more, which causes hyperglycemia (high blood sugar) and many of the clinical signs observed with diabetes mellitus. The common clinical signs of diabetes are similar to those of chronic renal failure and hyperthyroidism and include:

• Larger tufts in the litter 
• Excessive urination and thirst 
• An overweight or obese body condition with loss of muscle mass (especially in the spine or back) or weight loss 
• An overweight or obese body condition with loss of muscle mass (especially in the spine or back) or weight loss 
• Vomiting 
• Boredom or weakness

The treatment of diabetes mellitus can be expensive because it requires insulin injections twice a day that you must administer under the skin. It also requires dietary changes (a diet rich in protein and carbohydrates), frequent monitoring of blood glucose and frequent veterinary visits. With supportive care and chronic management, cats can do well. However, when diabetic complications develop (diabetic ketoacidosis, hyperosmolar syndrome, hyperglycemia, etc.), diabetes mellitus can be life-threatening.
