Give your cat a safe haven in the new home. A quiet room or walk in closet work fine. When the room is ready, open the carrier but let your cat decide when she's ready to come out. Some need to sit for awhile before they'll come out. Visit your cat's room often but don't force her to interact.
Cats like to take their time when making new friends.
The important thing to remember about cats is not to pressure them. Let your cat go at her own pace. They have an onsite staff to match cats and dogs with compatible people as well as a team of volunteers to answer any of your questions. So stop by Maddie's pet adoption center and take home a new friend. This cutie may like to hide - she is quite shy at first.
