The humans have been noticing that Audrey was losing weight, and yet having an extremely good appetite (she always has loved her fuds). When she went to the vet in January, he said she seemed overall healthy, and a good weight if he had not known what she weighed when she lived with her first Mom. He said he thought we should wait before performing blood tests, and to bring her back to have her weight checked in 1-2 months. Well, when that happened, she had lost a few more ounces, in spite of the humans having increased the amount of her food. So it was decided to do a full panel of lab work, with the two biggest possibilities being hyperthyroidism and diabetes.

So it turns out Audrey has hyperthyroidism. Her level of T4 hormone was very high, so the vet said it was not in question. He told the humans about the various treatment options, and so today she will start on some pills of methimazole to see how she responds. One of the treatment possibilities is to use radioactive iodine, but the vet said it was a good idea to try the medicine first anyway. So please have crossed pawsies that she will be a good girl and gobble down some pill pockets as well as she now gobbles down her food.
Any input from furriends who have dealt with this medical issue would be welcomed. We know it is quite common in older cats about Audrey's age.
