Radiocat Center in Northern California

SAGE Redwood City serves as home to Northern California’s only Radiocat Center for the Treatment of Feline Hyperthyroidism. Hyperthyroidism is a condition that causes behavioral changes, weight loss, excessive or decreased appetite, hyperactivity or lethargy, fever, rapid heartbeat and/or arrhythmia, shedding, increased water consumption and litter box output, diarrhea and osteoporosis. It can be fatal if left untreated. An alternative to medical and surgical treatments, Radiocat uses Iodine-131 injections to eliminate thyroid tumors.
