First off, congrats on adopting her

And on working on keeping her indoors!
Ideally wet food is better for them nutrionally, cats as a whole, don't take in enough water when they consume primarily dry food. So if they do eat dry, like you said, be sure to keep plently of fresh cold water available. Just play with it until you find a food she likes. Try to stick to higher quality foods for her, like chicken soup, felidae, wellness, eagle pack, etc... Not friskies, nine lives, or whiskas type of grocery store brands.
You can always even just feed wet as a once a day feeding and dry for the second feeding as an option too. Some wet is better then no wet when it comes down to it.
Good luck!
