Having a feline that lives through its elderly years in great health and happiness is a goal of lots of pet owners. The most popular endocrine condition in felines is hyperthyroidism. As cats age, they get more prone. Thus, we decided to discuss hyperthyroidism in cats, a necessary condition for feline parents to be knowledgeable about. You can see below the vital details concerning hyperthyroidism you should know.

What is hyperthyroidism?

Hyperthyroidism is also referred to as thyrotoxicosis. A swollen thyroid gland induces the overproduction of thyroid hormones in a cat’s neck. The benign tumor referred to as an adenoma is the most common reason for bigger thyroid glands. Cancerous thyroid adenocarcinomas create some extremely uncommon instances of hyperthyroidism. Although the beginning of feline hyperthyroidism is unexplained, nutritional lack or excesses and constant exposure to thyroid-disrupting substances may contribute.

Hyperthyroidism is a popular condition that mostly impacts middle-aged and elderly cats. Because of the widespread effect of thyroid hormones, several health concerns may emerge due to thyroid dysfunction. Prepare a cat and dog wellness plan for your pets to avoid these conditions.

What are the symptoms of a cat’s hyperthyroidism?

Hyperthyroidism in cats usually materializes itself in a large range of signs, some of which might be mild initially but increase as the problem worsens. Among the symptoms of feline hyperthyroidism are:

  • Diarrhea
  • Restlessness
  • Weight drop
  • Vomiting
  • Increased peeing
  • Hyperactivity
  • Appetite stimulation

Any signs that your feline might be coping with hyperthyroidism, despite how little, require an emergency trip to the vet and begin a treatment method. Hyperthyroidism triggers constant weight reduction in cats if the problem is not taken care of. This might cause them to build high blood pressure due to their constantly increased core body temperature, heart rate, breathing rate, and continuous agitation and uneasiness.

How is a cat’s hyperthyroidism diagnosed?

If a veterinarian believes a cat has a thyroid concern, they will do a physical exam and touch the cat’s neck to feel for an inflamed thyroid gland. The following analysis methods are ones your vet might suggest.

T4 Blood Test

T4 (thyroxine) levels that are uncommonly elevated are related to hyperthyroidism. In specific circumstances, additional testing of thyroid function can be required.

Complete blood count (CBC)

Anemia, swelling, infection, and platelet counts might all be determined with a full blood count.


This test searches for signs of chronic renal disease and infection in the cat’s pee.

Chemistry Panel

To examine for other conditions, such as chronic liver and kidney damage or disease, it is necessary to have a full blood panel done.

What are the treatments for a cat’s hyperthyroidism?

Therapy is required to restore the usual thyroid function in felines diagnosed with hyperthyroidism and reduce this condition’s symptoms. Fortunately, hyperthyroidism in cats may be effectively managed. The following are several of your treatment choices:


Thyroid hormone production might be managed by routine medication. If your feline takes a drug, T4 testing is crucial until its thyroid level is regular. When stabilized, your feline will require T4 screening to confirm that no medication adjustments are required.


This pertains to the actual extraction of the thyroid gland.

Radioiodine Therapy

Radioiodine therapy is a technique for handling thyroid ailments by irradiating the affected gland with radioactive iodine. Mostly, this therapy should only be conducted once on a cat to remove the condition.

Dietary Supplements

Your feline can consume an iodine-restricted prescription diet plan. They can not be cured with other foods or treats. Your vet may also consider checking kidney function and blood pressure.
