The majority of cases of hyperthyroidism in cats are the result of benign tumours. The most commonly identified abnormalities of the thyroid gland in hyperthyroid cases are follicular cell adenoma and multinodular adenomatous hyperplasia. 1% to 3% of feline hyperthyroid cases are caused by malignant tumours.
About 70% of affected cats also have enlarged thyroid glands . 10% of cats exhibit "apathetic hyperthyroidism", which is characterized by anorexia and lethargy. [65] The same three treatments used with humans are also options in treating feline hyperthyroidism (surgery, radioiodine treatment, and anti-thyroid drugs).
Female cats typically outlive male cats, and crossbred cats typically outlive purebred cats. [2] [4] It has also been found that the greater a cat's weight, the lower its life expectancy on average. [4] The current oldest verified cat alive is Flossie, who was born in 1995 in the United Kingdom. [10]
The average life expectancy of all domestic cat breeds was 11.7 years. Crossbreeds and Siamese came very close to that mark at 11.9 and 11.7 years, respectively.
Originating in Persia (modern-day Iran), Persians are one of the oldest and most recognizable cat breeds. They enjoy a life expectancy of 11 years. However, due to their distinct features, they ...
One treatment option is the use of radioactive iodine which directly destroys the overactive thyroid gland. The thyroid gland naturally uses iodine to produce thyroxine and other hormones. It cannot distinguish between normal iodine and the radioactive version. Administering the radioactive isotope causes the thyroid to take in the lethal ...
Maine Coon cats, with their majestic fur and gentle demeanor, are a marvel among feline breeds. Not only do they boast an impressive size, but they also have robust health and an interactive nature.
Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.. It is a common cause of hyperthyroidism [2] [3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).
