After my H left, my elderly pets started kicking off, one after another-- I lost 5 dogs and 2 pocket pet in the space of 2 1/2 years. One of the dogs had cancer-- it had already spread all over the place by the time it was discovered and was beyond treatment, but even so, I was able to keep him comfortable and happy for another year. I was amazed. He finally let me know when he was ready to go.
