The Clinton's cat, Socks, has gone to the great scratching-post in the sky.
Oddly, Socks was in the care of Clinton Secretary Bettie Currie, not in the care of the Clintons themselves. Wonkette:
And why was Currie watching over Socks? Because when Bill Clinton left the White House for New York, he brought along newer pet Buddy the Dog, who was soon run over and crushed to death by a car. Socks was supposedly going to live in Hillary’s fancy new house in Washington, but Hillary was never quite “ready” to allow her own pet — a helpless animal — to move to Georgetown. So poor old Socks was stuck with Mrs. Currie, or poor old Mrs. Currie was stuck with Socks.
Now I have to take a look at Mo Rocca's All the Presidents Pets. says P.J. O'Rourke: "Mo Rocca describes how U.S. political policy has been guided by presidential pets for more than two hundred years. Oh, and I suppose you have a better explanation?"
