When we got Tom he was 12 years old and a special needs cat. He had hyperthyroidism and we treated him with Tapazole (2 x 5 mg a day). His T4 numbers were above 90 and came down to 57 and then 50. We took him for another scheduled blood test yesterday and his numbers have dropped to 17. The vet says he is now hypothyroid.
Have been told the normal T4 range is between 20 and 60 with 30 being the ideal for a cat. The vet decreased the Tapazole from 10 mg per day to 7.5 mg per day. I did not think to ask why he would still be on the Tapazole if his numbers have dropped. I am awaiting a call back.
I understand hypo is rare in cats and of course we want to make sure he gets the best possible care.
Incidentally rescued old cats are great.
Thanks.
