Sneakers the cat is being reunited with his owner, hundreds of miles away from where the feline disappeared in 1996.
The long-haired black cat was given to Sacramento's Animal Care Services last week, where an employee scanned him for a microchip, a routine procedure.
The number on the chip was used to track down Allison MacEwan of Seattle, who said she placed newspaper ads and went door-to-door with fliers in a futile search for her lost cat a decade ago.
Officials on Wednesday said they aren't sure how the cat wound up in Sacramento.
MacEwan's daughter was 4 years old when her cat disappeared.
Officials said she is now looking forward to being reunited with her childhood pet.
