Donkey

A donkey is a sturdy, domesticated hoofed mammal known for its long ears, gentle temperament, and ability to carry heavy loads over rough terrain.

  • It turns out that donkeys are exceptionally good at repelling deer ticks. Now, researchers at the University of Massachusetts Amherst have harnessed that ability to create a natural bug repellent that proved as effective as DEET at fighting the pests.
