<human>: Can you give me the gist of the text in a nutshell?

Hey /r/cats! 
So a little backstory:
My mother's friend told her how she was going to have to put her cat down because of how her step-son is apparently allergic. My mother, being who she is, refused to hear it and took the cat in. Well, the cat has lived at that house all her life and now she's in our house. I completely understand how shocking this is to the cat. She's found a spot underneath my mother's bed where she refuses to leave from. She will come out when you go to pet her, very loving;always head butting and laying next to you. 

I suppose I'm a little concerned if we're doing everything right. The cat, Emma, will sit next to us, as long as we're in the spot she's in. She'll eat, drink, and use the litter box (all by her spot) as well. Is there anything else we should be doing to get her comfortable and feel safe to roam the house? We have not tried to pick her up and walk her around; we believe it's too forceful.
<bot>: New cat, stays in one spot, should we do anything else to get her comfortable to the house? Or is it a waiting game.
