Well, I'll have to give these questions some thought as well as the tests. BTW, Corky is doing OK, she seems to be going "more regular and better" now since we got her on the hairball stuff. She could still use a little more weight as always, she's 8 lbs, 10 oz a little down from her high of 9 lbs, 2 oz, but she is an older cat. B-) She's a real "chowhound," sometimes she pushes Boo (he's 17) out of the foodbowl and he is very much of an agressive chowhound too. B-)
Going to the airshow with Wings Over Pittsburgh to see the Thunderbirds fly. HEre's some pics of the T-Birds from the 2005 show as an appetizer:

I’m glad to hear a good report on Miss Corky. The pictures look great. Have a good time at the show.
