Hyperthyroidism in your cat – an interesting read!

What Is Hyperthyroidism ?
Hyperthyroidism is the most common hormone abnormality in cats. It is very rare in dogs. It is a disease of older cats. The average age at which it is first diagnosed is 8-13. Nine out of ten cats that develop hyperthyroidism are over ten years old.
In humans, the thyroid is a united two-lobe gland. Whereas in cats it is a ‘pair’ of glands. They are located on the underside of your cat’s neck along its wind pipe. Your cat’s thyroid glands regulate the speed at which your cat’s body metabolism works. It does this by producing a hormone called thyroxine or T- 4 that regulates the speed of all body processes. When your cat produces too much of it and its metabolic rate sores, it has become hyperthyroid.

What Signs Would I See If My Cat Is Hyperthyroid?
When your cat’s thyroid glands are over-producing thyroxine hormone, every organ in its body is affected. The pet’s kidneys, liver, muscles, heart, nervous and digestive system are all over-stimulated. This leads to a number of physical changes you can see. The signs that do occur all begin very slowly. As time passes, they gradually become more severe.

Weight Loss
Perceptive owners notice that although their cats are losing weight, their appetite is normal or increased. This is because the pet’s metabolic rate has accelerated and it is using up food calories just as fast as it can consume them.

Increased appetite
Most hyperthyroid cats are eating more to meet their increased need for calories. You will see them eating more and complaining when their food dish is empty.

Increased activity and restlessness
Often they are overly restless or hyperactive, and they may be more cranky and aggressive. Some have disturbed sleep patterns.
A few other signs of hyperthyroidism in your cat
Poor coat condition. Increased drinking and Increased Urination. Vomiting. Diarrhoea. Panting or difficulty breathing. Weakness or listlessness. If you suspect some of these symptoms may be present in your furry feline, get in touch with your local vet. They may run a simple blood test to check your cats thyroid levels.
