(1,846 posts)If she's willing to approach you, she's probably had pleasant contact with humans before, i.e., she's "socialized". If she's willing to come into your home on her own, let her in. If she wants right back out, let her go, as long as she doesn't feel trapped she'll trust you.
Second, it's probably best to keep her and the dog in separate rooms. She may have parasites or disease that your dog could catch. Once you get her checked out by a vet, introduce them to each other gradually.
On food- I look for grain free kibble and wet food, it's better for cats since they are carnivores rather than omnivores, though they will eat veggies, birdseed, and other things you wouldn't seem to think they would eat.
Both of my cats were strays and both adapted well to becoming indoor cats. They knew what the litter box was for almost instinctively, though I did have to show my second cat how to bury poop (which she took to in amazement, "Wow! I can bury this stuff?! Awesome!"
Here's pretty much the easiest cat shelter you can make if she won't come in or won't stay in.

I'm sure you'll get more responses from the professional cat folk soon.
Good Luck and thank you for having such a kind heart.
