Vanilla Coke fans are up in arms after Coca-Cola announced they’d be modifying their recipe to no longer include castoreum: a mixture of the anal secretions and urine of beavers that is also found in perfume.

Notably, the FDA approves the use of castoreum, which is categorized under “natural flavoring,” so you won’t know if you’re eating it.

Coca-Cola reassured Vanilla Coke fans that despite removing the ingredients their new recipe will still taste just like a beaver rubbed its crotch all over it.
