Could I get rabies from this cat scratch?

There's this stray cat that comes around and steals my cats cat food off our porch. It is always very nervous, runs away when I try to move towards it. But always looks back because it wants the food. Today, it was letting me pet it. It was coming over and seemed happy that I was. But still acting odd, I touched it's stomach and it's back legs and tail locked up. It moved in strange ways like that. Then, I accidentally was too rough, so it walked away. I reached out my hand, and it came back, swiped at my hand and cut two scratches in to my thumb.

I notice the strange movements, and how nervous it is, but there's no drooling or foam. I am really worried, will I get rabies? I know cats can lick their claws so saliva may have gotten in to the wound??
