When my 10 year old cat began behaving strangely, vomiting, constantly hungryy and hyperactive and the vet suspected thyroid problems which would have required either an upfront outlay of a good deal of money to diagnose and treat or that she be placed in thyroid medication for the rest of her life with constant blood test to monitor her condition ( resulting in greater expense in the long run) . Having this insurance gave me the ability to navigate the waters with a partner who had my back. In the end the scan ( contrary to the blood tests) revealed no thyroid problem and therefore no treatment necessary at this time. A change in diet was recommended. Thanks .
