An animal that dies must meet a number of conditions to become a mummy

The Natuurmuseum Fryslân showcases various animal mummies, highlighting the unique preservation process. Mummification occurs under specific conditions, often without scavengers or moisture. The exhibition features mummies like hedgehogs and otters, and emphasizes the prevalence of cat mummies over dog mummies due to their solitary nature. Additionally, the museum displays Egyptian animal mummies, which were often offerings to gods. Visitors can engage with interactive exhibits, including a game to test mummification skills. A reconstructed section of the Wiuwert church interior includes a rooster from a burial site, demonstrating ongoing research into animal mummification.
