I understand. My vet bills over the last couple of years have been ridiculously high, and the outcome for Sophie--whom we treated for thyroid disease--wasn't overly positive in the end. She was 14 at the time, too. I don't begrudge the money; it's just part of the bigger issue of how much to intervene in a older animal's health. Thyroid disease, in particular, is tricky in my opinion. Yes, it can be managed in a number of ways, but it also sometimes causes or unmasks other issues.

In any event, I hope your kitty starts to feel better soon, and that the other one returns home.
