We mice are very particular about which cats we have exploring around our homepage. But I suppose mudcatters are okay.The pretty music is the theme to a very silly American cartoon show (Dudley Do-Right) from the 1950's which made fun of the Royal Canadian Mounted Police in particular and Canadians in general. Which is not why we loved it -- it was just plain silly. It was part of the Rocky and Bullwinkle suite of cartoons.
