Here's why:
* Elephants don't have witch doctors: Elephants are animals and don't practice medicine or have spiritual beliefs like humans do.
* The concept of a witch doctor is human: "Witch doctor" is a term used for a traditional healer or spiritual figure in some human cultures.
So, you could say things like:
* An elephant healer: This is a more modern and neutral term.
* A shaman of the elephants: This plays with the idea of a spiritual leader but acknowledges elephants are not human.
Ultimately, the best way to refer to this concept depends on the context and the tone you want to convey.
