Observers say it is all but certain that the Federal Reserve will raise interest rates at its December meeting, even though the move is likely to slow economic growth. Many analysts have noted that the strong employment report released today may be enough to convince the Fed that the economy no longer needs extra support. But close Fed watchers say there are subtler indications. Fed chair Janet Yellen was recently seen taking back a kitten she had given to her granddaughter a few months earlier. “This tells us that she is mentally preparing to take something away from America, even though it will sadden and disappoint so many people,” said David Wessel, director of the Hutchins Center on Fiscal and Monetary Policy at the Brookings Institution. “The fact that she is keeping the kitten in a crate in her basement rather than having it euthanized, though, tells me that she might still change her mind.”
