Spot is my first cat to be diagnosed with this condition although I have a friend whose kitty has been successfully on methimazole for a year or two.
Spot is one of my ferals, so I seldom get my hands on her. Last Thursday I noticed her having trouble jumping up onto the bottom rung of a cat tree so I caught her (took about 15 minutes, usually takes 30) and took her in. The bloodwork came back hyperthyroid. I started the methimazole on Friday, once a day because she's hard to catch. The vet said if she stopped eating to cut the dose in half and start giving it twice a day. I did this on Monday, in addition to syringe feeding a couple times a day. On Wednesday I took her back in and left her at the clinic for the day. They gave her fluids and said to take her off the methimazole. The vet prescribed an appetite stimulant and said to call on Monday. He mentioned that her heart is racing and I can actually hear her breathing.
On Friday she started eating on her own a bit although she is either so weak or fatigued that she won't even stand. I've been warming food and offering it 5-6 times daily. I have to position the plate so she can eat. She is as close to death as I've seen an animal. I've read that in a small percentage of hyperthyroid cats that the methimazole causes anorexia, which appears to be what happened here. The vet mentioned trying her on a lower dose after we get her eating. I don't think surgery is an option. I don't think she'd survive it. And while the kidneys looked okay on the bloodwork, I have to suspect they might come in to play before all is said and done.
She's probably 12 years old and has never tamed, even though I've had her indoors for the past 8 years. Hard to know what made an animal that afraid of people.
Anyway, I have a feeling that I may have to make a decision whether or not to let her go. YES...there was a question in all of this. Has anyone had a cat with this same reaction to methimazole and what was the outcome? Is anyone aware of any treatment options other than the methimazole, surgery or radiation?
