Mr. Amber Cat had that and was treated with tapazole. I had asked my vet about the iodine treatment, but he didn't feel there was a need. Amber died of renal failure. He was 8 when he died.

Now Ruffles has it. She is 15. A heart murmur showed up at the time of diagnosis; very mild and my vet said not to worry about the heart murmur. She gets a very small dose of tapazole daily and she is fine.

You expected to notice a half pound weight loss? Over a 12 month time? Ease up on yourself! That is so minor and under their coat it is hard to see or feel such a small amount. I noticed Ruffles' problem when she lost 2 pounds in 6 weeks.

Best wishes to you.
