Animal Endocrine Clinic

Hypurrcat is a treatment facility dedicated solely to treating hyperthyroid cats with radioactive iodine (radioiodine, I-131). Founded by Dr. Mark E. Peterson, the preeminent authority in feline hyperthyroidism, Hypurrcat's reputation for providing high quality, specialized, and compassionate care has earned it international acclaim

Dr. Peterson and his team first documented feline hyperthyroidism just 45 years ago, and it is now recognized as the most common hormonal disorder in domestic cats. In 1980, Dr. Peterson was the first to use radioiodine to successfully treat cats with the disorder. In 2001, Dr. Peterson founded Hypurrcat, a radioiodine treatment center for hyperthyroid cats in Bedford Hills, New York. In 2005, Dr. Peterson relocated Hypurrcat to a larger space in Bedford Hills and also founded the Animal Endocrine Clinic. The Bedford Hills office was closed in early 2020. In 2009, Dr. Peterson opened an office on the Upper West Side of Manhattan in New York City
