SAN FRANCISCO — 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. But how the feline named Rayne Beau - pronounced “rainbow” - made it home two months after getting lost in Yellowstone National Park during a summer camping trip remains a mystery. Benny and Susanne Anguiano and their two cats arrived at Yellowstone’s Fishing Bridge RV Park on June 4 for the cats’ first trip to the forest.

But soon after they arrived, Rayne Beau was startled and ran into the nearby trees. The couple looked for him for four days, even laying out his favorite treats and toys. When they finally had to drive back to Salinas, California, on June 8, Susanne Anguiano said she was crushed but never lost hope she would find him.

“We were entering the Nevada desert and all of a sudden I see a double rainbow. And I took a picture of it and I thought, that’s a sign. That’s a sign for our rainbow that he’s going to be okay,” she said.

In August, the Anguianos received amazing news when a microchip company messaged them that their cat was at the Society for the Prevention of Cruelty to Animals in Roseville, California, nearly 900 miles (1,448 kilometers) from Yellowstone. He was only about 200 miles (322 kilometers) away from his home in Salinas. A woman who first saw Rayne Beau wandering the streets of the northern California city fed him and gave him water unti.
