Thank you for submitting your question regarding Colby Jack. There is an not an effective over-the-counter treatment for this disease. Hyperthyroidism in cats is most commonly treated with a prescription medication. Blood work needs to be carefully monitored though. Owners who are searching for a permanent resolution of the disease can pursue radioactive iodine therapy. Finally, there is a prescription diet available from Hill's that can control the disease as long as the cat eats this particular diet exclusively. I hope this information helps!
