1st off, that is SUPER awesome to anyone who will take in homeless animals. VERY good hearted thing to do, so many props to you/gf for that
2nd, yes take to vet, make sure when gets a lil older that she has enough toys, and it's going to happen that she'll want to lay on your laptop while you're using it, hehe, embrace their attention (or they'll demand it!) haha. They are super awesome animals.
