Canadian kitten ends up in Michigan a year later

An Canadian family has no idea how their kitten got across the Detroit River, but they're thrilled to have him back.

CBS Detroit affiliate WWJ reports Gus Gus, a three-year-old cat, disappeared in Kingsville, Ontario a year ago and turned up in a Northville, Mich., backyard, according to the Michigan Humane Society.

Gus Gus was identified by microchip after the family who discovered him brought him to a veterinarian.

"Chances are, maybe this cat got on the back of a truck, headed across the bridge, the cat got out and the rest is history," Humane Society spokesman Kevin Hatman told the station.

The kitten's human family, who feared he had been gobbled by coyotes, has nicknamed him the "International Cat of Mystery."
