Depending upon the type and stage of the disease, feline diabetes symptoms will vary from cat to cat. The prime candidates for diabetes are over weight older males, but cats of either sex and any age may be affected. The classic signs of the disease are excessive urination (polyuria) and excessive thirst (polydipsia). Early on in the disease, your cat may show only these symptoms, or none at all. In addition to polyuria and polydipsia, progressive symptoms may include an increase in appetite, while at the same time losing weight. In addition, sick cats will become lethargic. They also may develop diabetic neuropathy, a condition that causes weakness in the back legs. More severe symptoms may include loss of appetite, vomiting, and dehydration. Over time, afflicted cats may present with liver disease, secondary infections, and display poor hair coat. Additional symptoms can be brought on if a cat develops diabetic ketoacidosis. This is a potentially fatal condition that may cause breathing problems, weakness, vomiting and diarrhea. With proper treatment and disease management, feline diabetes can be controlled. There are two things you can do to help prevent the onset of the disease and reduce its effects in affected cats. First, ensure that your cat gets plenty of exercise, and second, ensure that your cat does not over eat.
