Raccoons Don’t Really Wash Their Food

Raccoons exhibit a behavior called dousing, which resembles washing food. Initially thought to be a cleaning action, it's now believed to be more about enhancing their tactile sensitivity. This behavior is primarily observed in captivity, where raccoons dip food in water. A 1963 study showed that raccoons douse food regardless of its cleanliness, suggesting it's not about cleaning. Hypotheses include enhancing sensitivity or an instinctual compulsion. Recent research supports the idea that wetting their paws increases sensitivity, aiding in food assessment. Dousing might be a fixed action pattern, similar to other instinctual behaviors in animals.
