My mom called me to tell me their one cat, Lucey, is now on thyroid medication (methamizole I think it is called). The vet has Lu on 5mg twice a day.

Isn't that a high dose?? I know I gave the same meds to my one FIV guy, and his thyroid was not controlled when he first came to me, and he was on 5mg. once a day (1/2 AM, 1/2 PM).

A woman in another rescue that I was fostering for said that it is almost a lethal dose for a cat.

Any thoughts on this??
