Hyperthyroidism is a common health issue affecting middle-aged to older cats, and it can have a significant impact on their quality of life. One of the most noticeable and distressing symptoms of hyperthyroidism in cats is excessive crying or meowing. As a concerned cat owner, it’s essential to understand the underlying causes of this behavior and how it relates to hyperthyroidism. In this article, we will delve into the world of feline hyperthyroidism, exploring its symptoms, causes, and effects on cat behavior, with a special focus on why hyperthyroid cats cry.
Understanding Hyperthyroidism in Cats
Hyperthyroidism is a medical condition characterized by an overproduction of thyroid hormones by the thyroid gland. In cats, this condition is usually caused by a benign tumor on the thyroid gland, which leads to an excessive production of thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in regulating various bodily functions, including metabolism, heart rate, and energy levels. When the thyroid gland produces too many of these hormones, it can lead to a range of symptoms, including weight loss, increased appetite, hyperactivity, and vocalization.
Symptoms of Hyperthyroidism in Cats
The symptoms of hyperthyroidism in cats can vary depending on the severity of the condition and the individual cat’s response to the excess thyroid hormones. Some common symptoms include:
- Weight loss, despite increased appetite
- Hyperactivity and restlessness
- Vocalization, including meowing, crying, and yowling
- Increased heart rate and blood pressure
- Increased shedding and poor coat condition
- Diarrhea and increased frequency of bowel movements
Diagnosing Hyperthyroidism in Cats
Diagnosing hyperthyroidism in cats typically involves a combination of physical examination, laboratory tests, and imaging studies. Your veterinarian may perform the following tests to diagnose hyperthyroidism:
A physical examination to check for signs of weight loss, hyperactivity, and other symptoms
Complete blood count (CBC) and blood chemistry profile to evaluate liver and kidney function
Thyroid function tests, including total T4 and free T4, to measure the levels of thyroid hormones in the blood
Ultrasonography or radiography to visualize the thyroid gland and detect any tumors or abnormalities
The Connection Between Hyperthyroidism and Vocalization in Cats
Vocalization is a common symptom of hyperthyroidism in cats, and it can be distressing for both the cat and the owner. But why do hyperthyroid cats cry so much? There are several possible explanations for this behavior:
Pain and Discomfort
Hyperthyroid cats may experience pain and discomfort due to the underlying condition, which can lead to vocalization. The excess thyroid hormones can cause a range of symptoms, including muscle wasting, joint pain, and gastrointestinal upset. These discomforts can cause the cat to cry or meow, especially if they are not receiving adequate pain management.
Anxiety and Stress
Hyperthyroidism can also cause anxiety and stress in cats, leading to excessive vocalization. The condition can affect the cat’s mood and behavior, causing them to become more irritable, restless, and vocal. This anxiety can be triggered by the cat’s awareness of their physical condition, as well as changes in their environment or routine.
Attention Seeking
Some hyperthyroid cats may cry or meow to seek attention from their owners. Cats are highly social animals and thrive on interaction with their human family members. If a hyperthyroid cat is not receiving enough attention or stimulation, they may vocalize to initiate interaction or to demand food, water, or other needs.
Managing Hyperthyroidism in Cats
While there is no cure for hyperthyroidism in cats, there are several treatment options available to manage the condition and alleviate its symptoms. The primary goal of treatment is to reduce the production of thyroid hormones and alleviate the associated symptoms. Treatment options may include:
Medications to reduce thyroid hormone production, such as methimazole
Surgery to remove the affected thyroid gland
Radioactive iodine therapy to destroy the abnormal thyroid tissue
Dietary changes to manage the condition and alleviate symptoms
Supportive Care for Hyperthyroid Cats
In addition to medical treatment, supportive care is essential to manage the symptoms of hyperthyroidism in cats. This may include:
Providing a balanced and nutritious diet to support the cat’s overall health
Ensuring access to fresh water and a clean litter box
Creating a stress-free environment to reduce anxiety and stress
Providing regular exercise and mental stimulation to manage hyperactivity and restlessness
Administering pain medication to manage discomfort and pain

What is hyperthyroidism in cats and how common is it?
Hyperthyroidism is a medical condition that occurs when the thyroid gland produces excessive amounts of thyroid hormones. In cats, this condition is usually caused by a benign tumor on the thyroid gland, which leads to an overproduction of thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in regulating various bodily functions, including metabolism, growth, and development. When the levels of T4 and T3 become too high, it can lead to a range of symptoms and health problems.
The prevalence of hyperthyroidism in cats is relatively high, especially in older animals. According to veterinary studies, hyperthyroidism is one of the most common endocrine disorders in cats, affecting approximately 10% of felines over the age of 10. The condition is more common in certain breeds, such as Siamese and Maine Coon, and is often associated with factors such as age, diet, and environmental exposure to certain chemicals. Early diagnosis and treatment are essential to manage the condition and prevent long-term complications, which is why cat owners should be aware of the signs and symptoms of hyperthyroidism and seek veterinary care if they notice any unusual changes in their cat’s behavior or health.
What are the symptoms of hyperthyroidism in cats and why do they cry?
The symptoms of hyperthyroidism in cats can vary depending on the severity of the condition and the individual animal. Common signs include weight loss, increased appetite, restlessness, hyperactivity, and vocalization, such as crying or meowing. Cats with hyperthyroidism may also exhibit other symptoms, such as increased heart rate, high blood pressure, and changes in grooming habits. The crying or meowing is often a result of the cat’s frustration, anxiety, or discomfort related to the condition. Additionally, some cats may become more demanding or affectionate, seeking attention and interaction from their owners.
The exact reason why cats with hyperthyroidism cry is not fully understood, but it is thought to be related to the hormonal imbalances caused by the condition. The excessive production of thyroid hormones can lead to changes in the cat’s behavior, including increased anxiety, stress, and irritability. Furthermore, the physical symptoms of hyperthyroidism, such as pain or discomfort, may also contribute to the cat’s vocalization.
