What hormones should I test my cat for? - briefly

If your cat is experiencing symptoms such as excessive thirst or urination, weight changes, or behavioral issues, it may be beneficial to test for thyroid hormones (T4 and TSH) and cortisol levels. These hormone tests can help identify conditions like hyperthyroidism and Cushing's disease in cats.

What hormones should I test my cat for? - in detail

When considering which hormones to test in your cat, it's important to take into account both common feline endocrine disorders and any specific symptoms or behaviors you have observed. Here are some key hormones that veterinarians typically assess:

  1. Thyroid Hormones (T4 and TSH): Hyperthyroidism is a common condition in older cats, characterized by an overactive thyroid gland. Symptoms include weight loss, increased appetite, and hyperactivity. Testing for thyroid hormones can help diagnose this condition. Additionally, hypothyroidism, although less common, can also be diagnosed through these tests.

  2. Cortisol: This hormone is produced by the adrenal glands and plays a crucial role in stress response and metabolism regulation. High cortisol levels may indicate Cushing's disease (hyperadrenocorticism), which can cause symptoms such as increased thirst, urination, and appetite, along with a pot-bellied appearance.

  3. Insulin: Diabetes mellitus is another common endocrine disorder in cats. Testing for insulin levels can help diagnose diabetes, particularly if your cat exhibits symptoms like excessive thirst, frequent urination, and weight loss despite increased appetite.

  4. Growth Hormone (GH): Although not routinely tested, growth hormone abnormalities can contribute to various conditions. Elevated GH levels may be associated with acromegaly, which can cause symptoms such as enlarged paws and facial changes.

  5. Sex Hormones (Testosterone and Estrogen): Abnormalities in sex hormones can lead to reproductive issues or behavioral problems. For instance, elevated testosterone levels might cause aggression or marking behavior in male cats, while estrogen imbalances could affect female cats' heat cycles.

  6. Parathyroid Hormone (PTH): Abnormalities in PTH can indicate issues with calcium regulation. Hyperparathyroidism can lead to increased calcium levels, which may cause kidney problems and other symptoms like lethargy and loss of appetite.

  7. Aldosterone: This hormone regulates sodium and potassium balance in the body. Elevated aldosterone levels might indicate hyperaldosteronism, a condition that can lead to high blood pressure and kidney issues.

When considering which hormones to test, it's essential to consult with your veterinarian. They can provide guidance based on your cat’s specific symptoms, age, and medical history. Regular check-ups and early detection are key to managing endocrine disorders effectively in cats.
