We were shocked when we returned home from a 10-day visit up north to find that Beegie had lost a lot of weight and was not eating. She was, however, as we had noticed in the past couple of months drinking more than usual. Took her to the vet and blood tests showed that she was in kidney failure. She was treated at the vet for two and a half days. Came home and still wasn't eating, but drinking an enormous quantity of water. Clearly she was suffering. This morning I sent her over the Rainbow Bridge.
