From the article: The animals that carry plague in the US are mostly rodents—rats, ground squirrels, and prairie dogs—and their fleas can pass plague bacteria to humans if they decide to bite us. Good news, though: The adorable little owls that live in burrows alongside those plaguey rodents seem to be immune. Although the owls have fleas capable of carrying plague, they are not infected—and their immunity could provide some interesting information to scientists studying the disease.
