Hi all, My kitty is 12 years old. Last year I put him on a diet, because he weighed 19#. He was also throwing up alot. I decided that he couldn't tolerate corn or wheat, so I started buying cat food that didn't have grains in it. He cried constantly, wanting his old Purina Cat Chow back, but it would make him vomit whenever I gave in. Well, he lost alot of weight........and didn't stop losing it. He weighs about 6# now. Several months ago I took him to the vet, and he was diagnosed with hyperthyroidism. The vet explained that it could be just the thyroid malfunctioning, or he could have a thyroid tumor. We would need an ultrasound to determine which it was, and then we'd need to decide if we just wanted to try the med, or radioactive iodine, or surgery. I decided to just give the med, since the other options would cost over $1,000, at least. Every time we put him on the med, he gets worse, and quits eating all-together. We took him off it for about 4-5 days, and he started eating again. Then we started back up on the med at a half dose. Today we brought that dosage up a little. He's looking awful and won't eat at all. The vet said there is a gel we could use on the ear, but the absorption is questionable. Does anyone use the gel, and does it still upset their stomachs? Has anyone heard of any other kind of treatment or med that could help our kitty? I don't think he has very much longer, if we can't get him to eat more. Thanks.
