Hyperthyroidism: 20.04.2021 – 21.05.2021

Can you believe hyperthyroidism affects approximately 10% of cats aged 9 years old or over?

What is hyperthyroidism?
It affects the thyroid gland, which produces the hormone thyroxine and is situated either side of the windpipe in the neck of the cat. The hormone thyroxine controls the body’s metabolism i.e the speed at which the body uses energy.
Hyperthyroidism is when the thyroxine gland enlarges and produces too much thyroxine. This over production results in a faster metabolism and stimulation of the nervous system leading to restlessness, increased activity or even aggression. If hyperthyroidism is left untreated it can lead to heart or kidney failure.

What to look out for?
• Looking thinner, loss of tone over hips and back.
• Increase of appetite
• Poor coat condition
• Becoming anxious, nervous, irritable, restless or aggressive.
• Lethargic and not wanting to interact.
• Increased use of the litter tray.
• Suffering from upset tummy or digestive issues.
• Increased breathing rates or even panting.

To help please complete the survey below it will allow us to review your answers and see if your pet may be in need of veterinary assistance. Even if you’re not sure if there are any changes with your cat why not take the survey for a little fun.

IMPORTANT NOTICE 1st September 2023

Dear Valued Client,
There have been some recent changes in legislation, which are designed to reduce the impact of drug resistance in certain categories of drugs. These have impacted the way we prescribe medicines to your pet.

Specifically, medicines used to treat parasites, including all prescription flea and worm treatments, can only be dispensed by our team if your pet has been examined by their registered veterinarian within 12 months. Although this has always been our policy the vet now has to annotate the clinical notes (rather than rely on automatic systems) with the exact flea and worming product and duration needed for the following year. Please bear with us as this logistical change may take a little more time than usual.

The other major change is that courses of antibiotics cannot be dispensed, extended or changed without your animal being physically examined. 

We are in the process of updating our recording systems to facilitate this process.

If you require prescription parasite treatment for your pet and they have not been examined by one of our vets within 12 months, you will be required to arrange an appointment.

We anticipate this will not affect the vast majority of pets, as they do receive their annual vaccinations or are otherwise regular visitors, for various reasons. They will therefore have received the necessary checks to be eligible for parasite treatment, without the need for a parasite consultation.

Thank you for your understanding.
Arberth Vets
