Jasper is a perfect example. This short haired brown tabby boy was living in one of Donna's colonies for well over ten years when his coat started to look bedragled and it appeared as though he was having difficulty eating. Donna thought that maybe he had come to the end of his life so she trapped him and brought him in. We anesthesized him, ran a blood panel, gave him a full examination and the only thing we found wrong with him was that he had bad teeth and was getting old. So we got his teeth taken care of and I offered to keep him in my guest bedroom thinking that I'd be holding him for only a brief time before he was to pass. (I have a soft spot for the old guys.) Well, shortly after we got his teeth taken care of, he started putting on weight and grooming himself again. Eventually he broke his way out of the guest room and joined my cats in the main house. Then he figured out how to get outside and joined the other outdoor cats. And this was his life for the past three years at my home.
