Sunday October 9th at 10 pm: Corduroy literally ran outside when we opened the door as we arrived home. We have not seen him since. It is with a heavy heart I make this post, announcing that Corduroy has most likely crossed the rainbow bridge. We miss him terribly and I hold out hope he will return...Logically, Corduroy won't come home. I appreciate all the support and love Corduroy has received--he was an exceptional sir. I am grateful we had an unbelievable, special, 27 years together. #oldestlivingcat #sircorduroy #throwbackthursday #meow #love #27andpouncing #stopdeclawing #thankful #morethan9lives 🌈 A photo posted by Corduroy (@oldestlivingcat) on Nov 24, 2016 at 1:24am PST Subscribe | UPI Odd Newsletter Subscribe SISTERS , Ore., Dec. 1 (UPI) -- A cat once named the world's oldest by the Guinness Book of World Records has gone missing from it's home in Oregon.
