A cat who got lost in Yellowstone National Park somehow traveled more than 900 miles to return home after two months, with help from the pet’s microchip, an animal welfare organization said.

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.

A couple in California feared their cat was lost forever after he ran away during a camping trip in Yellowstone. Two months later, however, he showed up in California.
