Our cat Sam was diagnosed with hyperthyroidism just over two years ago, when he was 13. He had been slowing down quite a bit and he was living pretty much downstairs, near the cat box and food, not venturing upstairs, and sleeping most of the time. The sleeping, of course, is not unusual for cats, but we really thought that he was on his way out.
We tried a couple of natural supplements, there were some slight positive results and and he was beginning to resist the supplements. We didn’t want to try medications with all of their side effects. About four months ago, we made the difficult decision to withdraw treatment and let nature take its course.
