You know the more I read about this cat, the more concerned I am about her well-being. I notice you said she didn't hear very well due to ear mites. It is more likely that she is deaf. It is not uncommon in white, blue-eyed cats.
The other issue is the sun. When white cats are rehomed from shelters here (and probably in other parts of the world) they are only to go to places where the cats will be kept indoors. This is because they are very prone to skin cancer.
Honestly, Galixy , by far the best thing you can do for this girl, of whom you are obviously very fond, is to have her spayed and bring her inside so that she is safe and loved and can have a truly good life.
