Offering the safest, most reliable treatment for Feline Hyperthyroidism

Hyperthyroidism is the most common hormonal disease of cats resulting from excess thyroid hormone, which puts significant and potentially fatal stresses on the body. Radioiodine therapy is the safest and most effective therapy available. It's less risky than surgery and doesn't require medicating your cat daily for years. Most cats stay a couple nights before returning home — happy and healthy.
