I am so glad you managed to get her away from that woman mf.
She is a little cutie pie!!
I am going to give you lots of reading to do about introductions. These are all tried and true methods. It will be up to you what you decide to try. Things may be a little different because the little one hasn't been around cats but she has been around other small dogs. She hasn't been allowed outside much either, has she?

Hopefully some of this info will help. Slow and steady wins the race. I'm sure after a while everyone will be living in harmony. If not - Manuel said he would take the dog, right?
