Hyperthyroidism in Cats - The Fact Sheet

Hyperthyroidism in Cats
by Dr. Arnold Plotnick

Section: Overview

Hyperthyroidism is a multisystemic metabolic disorder that occurs as a result of excessively high concentrations of thyroid hormones in the bloodstream. It is the most common glandular disorder in cats. Untreated hyperthyroidism results in increased cardiac output, and increased blood flow to the kidneys. Although the disease is treatable, in recent years it has become apparent that previously undetected kidney disease may suddenly be unmasked, and that known kidney disease may worsen in some cats after correction of their hyperthyroidism.

The disease is caused by excessive secretion of thyroid hormones by hyperplastic (overly large), usually benign thyroid glands. Although extensively studied, it is still not known why some cats develop hyperthyroidism while others do not.

Lump on Cat's Belly (Part 2) - This Gland is Your Gland, This Gland is My Gland

Part 2 (continued from Part 1)

First, I received Emma’s cytology report.  The discharge from the mammary gland, which I expected to show infection, came back “highly suspicious for carcinoma”!  Uh oh.  This was looking like a mammary tumor after all.  I looked back at Emma’s history.  Emma was adopted by the owner when she was around 3 years old.  Nothing was known about Emma before that, including her age at the time she was spayed.  This is important, because cats that are spayed before they ever come into heat almost never develop mammary tumors.  Cats that are spayed after one heat will still have a reduced chance of developing mammary tumors in the future.  After two heats, however, any mammary tumor-sparing effects of spaying are lost.  This is why we encourage people to have their cats spayed at 5 ½ or 6 months of age.  I still encounter people who cling to the myth that it is best to let cats go through one heat cycle before spaying.  This is a ridiculous notion, and a dangerous one.  I suspect that Emma was spayed later than 6 months of age.  Unfortunately, we’ll never truly know.

Lump on Cats Belly (Part 1) - I Want To Hold Your Gland

Two weeks ago, I was presented with a very aggressive 15 year-old cat for evaluation of a “lump on the cat’s belly”, as noted in our appointment book. Emma had been adopted as a 3 year old by her owner.  She was eating and drinking well, was drinking water normally, vomited occasionally, and that’s about it.  No coughing, no sneezing, no diarrhea… no problems in general.

Emma was a handful.  She had to be muzzled before I could examine her.  I couldn’t examine her eyes or her teeth very well, as a result.  When I got to her belly, the owner showed me what she was concerned about.  It looked like there was some discharge coming from the last nipple on the left side.

When it comes to anything involving the mammary glands, veterinarians start to worry.
