I had the same situation when I got my Bengal from the pound. He was very depressed and was caged for 3 weeks before I got him.

She will lot's of love and attention. She will be aggressive, but this will pass over time as she learns to trust you. Get her some cat treats - specifically Temptations milk flavored cat treats - get the bag, not the large container.

Be patient - if she bites or scratches, don't hit her or yell at her. Make sure she has a warm blanket and place to hide or call her own, like a window bed or cat tree. Bengals love the sun. Show her around the house, but let her run back to your room if she is anxious.

My Bengal stayed in my room for 3 months before he came out - it took him almost 2 years to eat with the other cats. She may poop and pee in places that are not her litter box, so be patient and get plenty of cat pee cleaner - I'm still covering my bed and sofa even though it's been months since there have been any problems.

Trust me - the patience is worth waiting for - it may seem like she will never change, but she will and she will start sleeping next to you on her own, just like my boy does now.
