Here's my original thread
I originally posted about Motley a couple of months ago, she had been on Vidalta for her thyroid and it had started making her projectile vomit everywhere a couple of hours after taking it. She lost a lot of weight and I was very worried about her.
She was tested for absolutely everything (ultrasound, lung x-ray, blood, urine and faeces tests) and everything came back fine.
Well - today she had a check up after being on Felimazole for just over a month. She has put on half a kilo! 
The vet was very impressed with the condition of her coat and said it was amazing for a hyperthyroid cat. She's had another blood test and the results should be back on Tuesday - but I'm cautiously optimistic! :)
