Rc was adopted from a shelter. When I sprung him from cat jail, he only had one good eye & digestive problems. He is now a fat happy spoiled cat. My vet calls him the million dollar cat as he ended up having to have the eye removed & then got hyperthyroidism & had to be treated for that, which entailed a trip to a special clinic in Georgia, where he did have radioactive iodine injected, successfully I am happy to say.
