Has Zoe been around any cats in her life? If so, how did she act?
I've never introduced a kitten to a dog, but I've introduced two dogs to two cats on different occasions.
All I can really say is never leave her alone with the kitten until you are for certain they'll get along. I still don't leave Skylar alone with any of the cats.
I don't really know how to help much, but I know others here on PT will give you better advise than me.
Good luck!
