As you can see in the above video, before treatment she was getting ready to go into a hyperthyroid crisis (sometimes called a thyroid storm). She was experiencing severe heart issues, including tachycardia (rapid heart rate) and ventricular arrhythmia (irregular heartbeat), due to her hyperthyroidism. She was anxious, agitated, panting, and underweight.

The second video shows the same cat, after she has been cured of her hyperthyroidism with a radioiodine treatment at the Hypurrcat Spa. This video is taken 3 months after her I-131 treatment. She is now relaxed and she has gained weight back. Recent blood tests reveal that her T4 level has returned to normal, meaning that she is now cured of hyperthyroidism.
