Thyroid Problems


Hyperthyroidism is over production of thyroid hormone and can be one of the most common hormonal conditions affecting older domesticated cats.

The most common presenting symptoms are:

Rapid weight loss,

Increased appetite

Rapid heart rate



Other symptoms include hyperactivity, possible aggression, an unkempt appearance, and large, thick nails. About 70% of afflicted cats also have noticeably enlarged thyroid glands.

If left untreated hyperthyroidism can be fatal but it can be very easily controlled and treated with medication or surgery.
