Hello, I suggest you make sure your kitten and dog is ok around pitbulls first! Maybe a neighbor has a pitbull or a family member they can try to interact with! Then, you can rescue the animal that you and your family is okay good to interact with or whatever you want! Thanks
Pitbulls at least the older ones usually don't like cats. But I adopted a Pitbull 7 years ago from Barcs and she is the best dog I have ever had. Their meet and greet is great! Good luck. It's the best place to adopt!
I am not sure about the cat, but I do know you would need to bring the dog you already own to meet any dogs you potentially adopt to ensure they get along.
