females will do it for the very same reason as the males. they are saying that "THIS, this RIGHT here, its MINE" and they can also use their trail to help navigate unfamliar places as they use their sense of smell much more then their sight.
Doe and Buck scenting.. or just peeing?
I know that Bucks pee a lot to mark their scent, but why do Does do it? I've heard people say that it's because they are ready to come into heat, but how is that possible when I have seen female rats pee everyday, when they are out playing if they only come into hear every 5 days or so, or whatever it is. (Please correct me if I'm wrong. 
)
I've also heard they are scent marking, but don't do it as often or as much as the Bucks.
Thanks ahead of time!
