Socks: R.I.P.

Socks, who was born in 1989, was put to sleep about 10 a.m. at Three Notch Veterinary Clinic in Hollywood, Maryland, said veterinary assistant Rae Dera. Veterinarians say he was probably either 19 or 20 years old.

The cat had been losing weight since November and had been treated at the clinic, Dera said. He had been suffering from a cancer in his mouth and jaw.

Since the Clintons left the White House in 2001, Socks had lived with Betty Currie, former President Bill Clinton's secretary. The Clintons were known to have visited Socks, and Currie, when in Washington.

He had been a stray and was adopted by Chelsea Clinton, the Clintons' daughter, when Bill Clinton was governor of Arkansas.

"Socks brought much happiness to Chelsea and us over the years, and enjoyment to kids and cat lovers everywhere," Bill and Hillary Clinton said in a joint statement released by the William J. Clinton Foundation. "We're grateful for those memories, and we especially want to thank our good friend, Betty Currie, for taking such loving care of Socks for so many years."
