Hyperthyroidism in Old Cats

This is a common hormone disorder in older cats, but is rarely seen in cats under 8 years old. The average age for a diagnosis is 13 years. In fact, 95% of cats with hyperthyroid disease are 10 years old or older. Hyperthyroidism is caused by a benign tumor of the thyroid gland called an Adenoma.

Thyroid hormone production is increased, but too much can cause hyperactivity in all body functions. The changes are subtle and often people put weight loss and poor coat down to old age.

Hyperthyroidism can lead to high blood pressure and heart disease.

Symptoms to look out for are vomiting, diarrhea, poor coat condition, restless, increased thirst, fast heart rate, increased hunger, and weight loss. These symptoms will worsen if they are not treated.

Most cases of hyperthyroidism are caught in the early stage because the owners notice the changes in their cat and seek the help of their vet straight away.

It is important to decrease high blood pressure so that the other issues that accompany this will also subside. There are three types of treatment available for high blood pressure:

  • Food. There is a specific thyroid diet which has only just enough iodine for normal thyroid function.
  • Your vet can recommend and prescribe a suitable Medication.
  • Surgery is available, but you should understand the risks to your pet.

Like most illnesses, early identification and treatment will give your cat a better chance of survival.

We are open for home Euthanasia

In order to safeguard you and our vets and to comply with Government regulations there will be a series of requirements you must agree to before we can confirm a home visit:

1. Only one and the same family representative can be present during the vet’s visit, other family or friends must say their goodbyes before the vet arrives at your home

2. There must at all times be a two meter distance between the family member and the vet.

3. We are aware that this may be distressing but due to the current Government restrictions we will not be able to arrange home visits without strict compliance to these requirements.

4. If, when the vet is in your home, you do not comply with these requirements the vet may end the home visit at any time to protect their own safety

5. Thank you for your understanding and consideration in these very difficult and dangerous times.
