Symptoms of Cat Thyroid Problems

Cat thyroid problems are extremely common in older felines. There are specific symptoms that can indicate a thyroid problem. Fortunately, this condition is highly treatable, so owners of older cats can increase the length and quality of their affected pets' lives as long as they receive prompt treatment.

Description

Hyperthyroidism is a cat thyroid problem caused by too much thyroid hormone. A tumor develops on the thyroid, resulting in out-of-control hormone production. The excess hormones have negative effects on all of the cat's organs.

Timeframe

Hyperthyroidism is the most common endocrine condition in cats that are age 7 or older. According to PetFinder.com, less than 6 percent of cats with thyroid problems are 9 years old or younger. These problems happen most often between 12 and 13 years of age.

Symptoms

The symptoms of thyroid problems in cats are rapid loss of weight despite an increased appetite, rapid heartbeat, weakness, increased drinking and urination, vomiting, unkempt hair and no little or no tolerance for heat.

Diagnosis

When a cat aged 7 or older is showing these symptoms, the veterinarian performs a blood test to check for thyroid problems. He will also perform a physical exam to see if there are other symptoms.

Treatment

According to veterinarian J. Kris Hankinson at ThePetCenter.com, cats who are otherwise healthy can be treated with radioactive iodine or an operation to remove the thyroid gland. When this is not possible, a medication called methimazole (brand name Tapazole) is given to lower the cat's hormone levels.
