The best approach for you depends on your age, physical condition, the underlying cause of the hyperthyroidism, personal preference and the severity of your disorder: 1  Radioactive iodine. 2  Anti-thyroid medications. 3  Beta blockers.  Surgery (thyroidectomy). If you're pregnant or otherwise can't tolerate anti-thyroid drugs and don't want to or can't have radioactive iodine therapy, you may be a candidate for thyroid surgery, although this is an option in only a few cases. In a thyroidectomy, your doctor removes most of your thyroid gland.
Fox squirrels have been known to live to 18 years old in captivity. Under natural conditions the average lifespan is 8 to 18 years old, though most squirrels die before they reach adulthood. Fox squirrels spend most of their time in trees during the day.
Larger tree and flying squirrels (like fox and gray squirrels) usually have gestation periods of anywhere between 38 and 46 days, while smaller species often gestate for less than 38 days.heir abundance is perhaps supported by the fact that there are well over 250 squirrel species, including types of ground squirrels, tree squirrels, chipmunks, marmots and flying squirrels.
