Cat's Night Out


Just like other animals, cats can develop many types of disease.

Click on the tabs below to read more about several of the most common diseases affecting cats.


What is feline hyperthyroidism?
Feline hyperthyroidism is caused by an over-abundance of circulating thyroid hormone. In the vast majority of cats, excess thyroid hormone secretion is caused by a benign thyroid tumor (adenoma).

Clinical signs:
Signs of hyperthyroidism can include any of the following:

  • Increased appetite
  • Weight loss
  • Chronic vomiting
  • Increased water consumption
  • Unkempt haircoat
  • High blood pressure
  • Heart abnormalities

Hyperthyroidism can be diagnosed by measuring the circulating T4 level – an elevated T4 level is diagnostic for hyperthyroidism. In some cases of hyperthyroidism, however, total T4 may be normal and further thyroid testing is needed for diagnosis.

Hyperthyroidism can be treated in one of several ways:

  • Surgery
  • I131 Radioactive Iodine Therapy
  • Medication
  • Prescription diet

Type 2 Diabetes Mellitus

What is feline diabetes?

In healthy animals, food is broken down into digestible components, including glucose. Glucose then enters the bloodstream and is transported throughout the body to supply energy to body cells. Insulin allows this circulating glucose to enter the cells. In the absence of adequate or functional insulin, glucose cannot enter the cells and starts to accumulate in the bloodstream. The body’s cells are also not supplied with the energy they need.

Diabetes can be caused by a lack of adequate insulin production (Type 1) or by the production of non-functional insulin (Type 2). Feline diabetes is most often Type 2, meaning cats produce insulin but are essentially immune to its effects.

Factors predisposing to the development of Type 2 Diabetes:

Obesity is a significant underlying cause of Type 2 diabetes in cats. Excess body fat results in gradual insulin resistance, which can ultimately result in the development of clinical diabetes. Genetic predisposition may play some role as well, with certain breeds being more likely to develop diabetes than others.

Clinical signs:
Signs of feline diabetes can include any of the following:

  • Increased thirst
  • Increased urination (urinating more frequently than usual, larger clumps of urine in the litter box)
  • Weight loss, despite a good appetite (although diabetic cats are taking inadequate nutrition, glucose from the diet cannot enter their cells to supply them with energy)
  • Lethargy, or decreased energy and activity
  • Unkempt haircoat (poor grooming, dull coat)


Insulin therapy: As diabetic cats become insulin resistant, they begin to require extra insulin to move glucose from the bloodstream into cells. Diabetic cats, therefore, require daily insulin injections to regulate their blood glucose and manage their diabetes. Several types of insulin can be used to treat feline diabetes, each insulin type varying in its duration of action. Strict insulin therapy is needed for excellent glycemic control in diabetic patients.

Diet: Perhaps equally important to insulin therapy is appropriate dietary management. Diets that are high in protein (energy) and low in carbohydrates are essential for good glycemic control. This diet is also needed for healthy weight loss. Obesity often causes insulin resistance to develop in the first place, and weight loss can potentially help diabetic cats to become more sensitive to insulin.
With strict insulin therapy and weight loss, some diabetic cats can even go into diabetic remission, meaning their diabetes resolves, and they no longer require daily insulin therapy.

Maintaining a healthy weight: Weight management is perhaps the most important way we can prevent feline diabetes—maintaining a healthy body weight can prevent insulin resistance from developing. Feeding a balanced diet, an appropriate number of calories, and maintaining adequate daily exercise and activity are all important for keeping your cat fit and trim. If your cat is overweight, weight loss is needed to reduce its risk of developing diabetes. WTVC specializes in nutrition and helping cats achieve healthy weight loss—call the clinic today to schedule an appointment to discuss your cat’s weight and ways you can help your cat to achieve an ideal body weight.

Regular check-ups: Bringing your cat to the vet on a regular basis (yearly for younger cats, and every six months for senior cats) is important for assessing your cat’s diabetic risk and detecting the disease early. Regular wellness testing plays an important role in detecting early diabetes—cats with the early disease often have elevated blood glucose and glucose in their urine, even without showing obvious signs of diabetes at home. We recommend annual wellness testing for all cats.

Feline Cognitive Disorder

Just like other animals, cats can suffer from cognitive decline as they age. Feline Cognitive Disorder (FCD) can cause confusion and disorientation, leading to house soiling, vocalization at night, and reduced interaction with family members. Typically, FCD begins to develop in a cat’s geriatric years – or when they are over 13 years of age.

Fortunately, treatment is available in the form of FDA approved drugs and prescription foods. We have also seen good results with a product called Neutricks, a nutritional supplement made by Quincy Animal Health right here in Madison.

Studies on Neutricks in dogs have shown this supplement to be twice as effective as the FDA approved the drug, with no safety issues. Interestingly, the active ingredient in Neutricks is Apoquerin, which has been identified in jellyfish as being a neuroprotective protein. There is even a human product made by the same company.

According to the Association for Pet Obesity Prevention – in the October 2017 clinical survey, 56% of dogs and 60% of cats were classified as overweight(body condition score (BCS) 6-7) or obese (BCS 8-9) by their veterinary healthcare professional. These results indicate an estimated 50.2 million dogs and 56.5 million cats are above a healthy weight, based on 2017 pet population projections provided by the American Pet Products Association (APPA). In 2016, APOP found 54% of dogs and 59% of cats were overweight or obese in the U.S.

Periodontal Disease

According to the American Veterinary Dental College – Periodontal disease is the most common clinical condition occurring in adult dogs and cats and is entirely preventable. By three years of age, most dogs and cats have some evidence of periodontal disease. Unfortunately, other than bad breath, there are few signs of the disease process evident to the owner, and professional dental cleaning and periodontal therapy often comes too late to prevent extensive disease or to save teeth. As a result, periodontal disease is usually under-treated, and may cause multiple problems in the oral cavity and may be associated with damage to internal organs in some patients as they age.
