Thanks Aerogirl, Laura and Henry and Fern (you stuck in there as I was writing this) for your kind sentiments about Weaver.
He is "in hospital" at the vet and we hope to learn something by tomorrow afternoon. I'll sure keep you updated.
I realize, especially many of the younger set today, think such concern, especially about cats, is rather frivoulous. But when one is getting on in years and it's just the two of you, people our age and yes, even older, regard their pets as their "furry children" as opposed to just a "dog" or a "cat." Don't misconstrue that millions of younger folks feel just as strongly as we about their pets. It's just that it becomes more pronounced as one grows older.
