Sammy is 12 years old. That is a respectable age for a cat, so I was very happy to hear from his owner that he was still very well in himself and she had no concerns at all. The purpose of my visit was a routine health check and vaccination and based on Sammy’s good report, I was expecting to issue him with a clean bill of health. However as I began to collect a thorough history, it became apparent that things were not as simple as they had first appeared. ‘Now that you mention it, Sammy HAS been drinking more than he used to, but I thought that was normal for older cats so I didn’t think twice.’ He had also had a great appetite lately, in fact he’d been eating an extra pouch a day, and he had been more talkative lately. All things that his owner had associated with good health but could actually be signs of illness. On physical exam it turned out he had lost some weight and muscle mass, and that he had a lump under his neck. A blood test was recommended and the results confirmed hyperthyroidism. He was started on medication and is now back to his normal self, his owner couldn’t believe the difference! She was surprised how the changes had happened so gradually that she didn’t notice them, but was very happy to have her old cat back. And Sammy certainly agreed…..
