Hi there, am hoping someone out there can offer advise. My elderly cat has in the last week been diagnosed with hyperthyroidism and has since gone from having a very healthy appetite to only licking the jelly from his food. I thought it was perhaps a dental issue but he occasionally still eats a few biscuits. I know he has gone through picky periods with his food but never quite like this. He has now lost a considerable amount of weight in a short period of time. He still seems quite happy, likes to be fussed and will purr away happily. The vet has commenced him on 2.5mg Felimazole tablets twice a day, that is another battle I am struggling with.
