Not a lot, but where do you live?
I've trapped a lot in my youth, but not lion (we never had them then in Wisconsin). We have them now.
I know they have a territory (that may change if they are merely moving through), but if they are in an established territory, they roam around in it. Consequently, they won't likely be in the same place the next day, but they will probably return to your place in their rounds, particularly if they've been successful in hunting.
They will return to a fresh kill, so this is a great opportunity to trap one if you find a kill.
They are curious.
This is the best site I've found in a short search:
Mountain lion control Felis concolor and cougar management
You could call them if you like excitement.
Keep your kids inside - period. Go outside armed (it really isn't hard to get used to).
