My cat who was being treated for hyperthyroidism with methimazole suddenly became quite ill last week. His white cell count was down to 1000 and according to one blood test his platelets were (seems radically low so I suspect it might have been an error) 13,000. BUN, Creatnine, and Bilirubin were all elevated but his ALT was normal. Upon release from the hospital (after IV treatment) there was much improvement but his ALT which was normal was now elevated.
My concern is this. How to proceed. I love this cat very much and do not want to cause him undo suffering. I am concerned about possible side effects of alternative meds and we have ruled out radio active iodine treatments. My goal for him is optimum health, comfort, and humane treatment over simple longevity. One vet recommended against surgery because he was high risk, and another said that if his next blood tests were normal that surgery was an option. I am happy to proceed with surgery if there is some likelihood of a positive outcome. Unfortunately with a different cat of ours he ended up having to be put down 2 months after surgery making the end of his life a misery. I do not want that to be this cat's fate. Any thoughts are appreciated.
Thank You
