Hyperthyroidism (overactive thyroid) is very common in cats as they get older, affecting almost one in ten cats by 10 years of age, early recognition of signs can really improve your cat’s life.
The thyroid hormones govern the overall speed of metabolism, so having an overactive thyroid means that everything is working much faster than it ought to be. These cats will typically lose weight, despite having an (often massively) increased appetite. They may also seem manic / skittish, be increasingly vocal, have rapid heart rates, poor coats and suffer with diarrhoea / vomiting.
If you think this might describe your older cat, then it is well worth having a blood test. If left unchecked, this disease puts real stress on the other organs, particularly the eyes, heart and kidneys. It can lead to blindness and even sudden death.
Treatment is typically by an oral liquid or tablets, is relatively inexpensive and usually very effective.
