I'm back from California, now here's something completely irrelevant

I thought there was an English word "stoor" that meant animal droppings.

Checking dictionaries, no such word appears to exist. (I mean, there are English meanings for "stoor", but they're all kind of obscure or specific to UK dialects, and none of them are that.)

I am really wondering where I got this idea. A misreading of "stool", maybe? Unfortunately I don't think it's really possible to answer this question...

EDIT: Oh. I was thinking of the word "spoor". Oops.

EDIT AGAIN: Which doesn't actually just mean droppings! Huh!
