Your little girl is absolutely gorgeous, and I agree with Fluffys mum, slow and small steps are always better. I'm sure she'll be fine, and once she settles in, will soon take over the house.
With all my Raggies, I've done very slow introductions, keeping them in one room even for some time, they've all been fine and in a short while settled in really well.
They give me purrmission to live with them, so long as the food, water, play time, tummy rubs etc. etc. are done, they seem pretty satisfied with my service. LOL
I'm hoping to get my new baby in about a month and will be doing the same with him too. x
