*<font color="white"> Shakespeare was treated with methimazole. The licenced product is called Felimazole® (Arnolds Veterinary Products). The initial dose is 2.5mg twice daily. By re-taking the total T4 level 3 weeks later the adequacy of the dose can be determined. It is important to satisfy yourself that the client is managing to give the tablets since in that case the cause of a second high T4 may be due to failure of the owner to administer the tablets! Another product, Vidalta® (Intervet UK), containing carbimazole has recently been licenced and has the advantage of only requiring once daily dosing. There are other treatment options. Surgical removal of the thyroid gland is possible. However, with unilateral excision there is a risk of recurrence (even if the other gland looks normal) and with bilateral excision there is a risk of iatrogenic hypoparathyroidism. Since hyperthyroid cats are high risk anaesthetic patients, they should be treated medically first. Another treatment, the current treatment of choice, is radioactive iodine treatment. Radioactive iodine concentrates in the thyroid gland and destroys it. However, few practices carry out this treatment, so the animal must usually be referred and the cat must remain at the centre for a long time. </font>
