Funny how the non-natives don't have a clue what a totem actually is.
"Totem" comes from a word that means "clan". Your totem is the symbol of the clan you were born into, kinda like how a European coat of arms is a symbol that represents your family.
They aren't "animal spirit guides", and you don't find or discover it. That's all just made-up crap from the new-age movement, falsely attributed to being a native american belief. It isn't.
Not all totems are even represented by animals. My clan is the salt clan.
So can you have a totem animal if you're not native american? No. Because you don't have any clan.
Just like I don't have a scottish tartan or a European family crest.
Navajo- native american, but don't have a totem animal.
