@Frank Apisa,
I thought we'd lose her last winter--she didn't do well at all. When the spring came along, though, she cheered up considerably. Basically, she's one of the most cheerful and positive persons i've ever met. Nothing gets her down for long. She constantly amazes me as she asjusts, on an almost daily basis, to here failing eyesight. She does not seem to be in pain (she did in the winter, when we gave her aspirins and pills for her joints), and she still has her motor skills. So often, of an evening, she'll suddenly look up at you and smile. For her, i believe, life is still good. So long as that is so, i'll put up with whatever it takes to keep her going along and happy.
