A couple was reunited with their cat Rayne Beau aka Rainbow, who was found 800 miles away from where he vanished, after he vanished during a camping trip in Yellowstone.

The owners of Rayne Beau, the 2-year-old Siamese cat, have no idea how their cat made it back, but call his return a “miracle.”

A gray cat living an extraordinary life of visits to the beach and trips to the lake went on his biggest adventure alone: traveling hundreds of miles from Wyoming to California.
