In addition to using scent to reinforce social ties, some species of ground squirrels anoint their bodies with rattlesnake scent (a smell reminiscent of cucumber) as a means of concealing their odor from their chemosensory rattlesnake predators. They do this by chewing on molted rattlesnake skins, then licking their fur. 

 

Other Nations is a perfume for humans inspired by squirrel's use of olfactory camouflage. The scent, created in collaboration with Dannielle Sergent of COGNOSCENTI perfume, was shared during public events to create networks of community between humans and more-than-human animals. The perfume has animalic base notes of fur and musk, middle notes of acorns and prairie, and a whisper of rattlesnake.
