Our kitty has long since ceased being radioactive but she continues to find ways to be expensive. Before the hyperthyroid treatment, Maggie had a small lump on her neck that was about the size of the head of a pin. It has grown. We took her in today and it’s a tumor. Sigh. She’s going to be sixteen years old this summer, so we’re trying to balance the cost against projected lifespan. It’s not an easy equation.
