Anya, she’d probably prefer a martini.

Some cats have exceptionally soft fur. Ringo looks as if she might be one of those. Am I correct? or is it just the color and reflectiveness that makes her look that way?

As to the clean sweep, it’s merely the most extreme of a typical housecat behavior toward tables. Samantha jumps on a table and immediately begins drinking any water she finds there (even from a glass; she hasn’t tipped one over yet, not even during hasty retreat as we chase her off) and investigating anything she thinks might be edible. Ringo is merely assisting you with the housekeeping: if there’s no food or drink there, nothing else on the table is important.
