Disneyland’s feral cats have formed a legendary nocturnal alliance with the theme park, patrolling after dark and keeping rodent invaders at bay. The feral cats of Disneyland are the unsung, whiskered custodians of the Magic Kingdom—and possibly the strangest Disney cast members you’ve never seen.

What keeps Disneyland’s secret army of feral cats so effective is a decades-old truce: Disney quietly welcomes these feline exterminators, even installing “cat stations” with food and shelter around Sleeping Beauty Castle and Haunted Mansion. Thanks to this unique pact, Disneyland’s secret army of feral cats ensures Mickey’s kingdom is mouse-free, letting the park’s fantasy thrive without uninvited rodent guests.
