Errr maybe see where you're going to live and how much money you've got first
Cats are pretty independent animals but they still need space, food, doctor, and so on (yes I've forgotten the spelling for animal's doctor in English and I'm too lazy to search)
While studying I often came back from school at 10pm (left home at 8am), and I barely had enough time to go shopping for groceries once every 3 weeks. Sure, you might not be at that level of the human disaster scale but I suggest taking time before making such an important decision (that's a Life we're talking about here, you don't want a sad cat)
I suggest starting with a plant. The succulent king. Those things never die lol

what does it feel like to live alone?(especially as a woman). im still 18 and ive been wanting to live alone for a long time.any advice or anything i should know?
