Thanks everyone, just wanted to post a little update.

She is doing pretty well, adjusting to living indoors nicely, though she occasionally cries to go outside or tries to climb the window in our living room to get out. She has claimed a box for herself , and she's doing pretty well adjusting to using the litterbox, though the other day she went into Domino and Tallulah's litterbox, then came back out and pooped beside it , but last night she pooped in her litterbox, so I was really excited! Still waiting to see if she's pregnant or not. She's eating like a little piggy, but that could be because she's never had an abundance of food too. So, I'll keep everyone updated!
