Could this be a animal scratch?

I just got home from work and noticed a scratch on my leg. It's a little deep enough to draw some blood and make it sting, and my fear is walking in the dark. When I went out to my car I got in right away, kinda quickly coz it was a dark parking lot, and then when I got home I ran in, because it was windy. I didn't see or hear any animals on the way, and I'm wondering if I just maybe even scratched my leg in my car ( since i got in pretty quick )... Its kinda high up on my leg and just one singular mark nothing else, I know where my mom's dogs scratch me they leave 2-3 marks marks in a row.. and plus could this have any chance of rabies...?
