Currently, I have a dog, a cat and three ferrets. The last member to join my household was my cat. He is a 4 year old Siamese cat. He was raised from a kitten with my (then) four approximately 3-4 year old ferrets and ten year old dog. Now my ferrets are 7-8 and my dog is 14, so they are all seniors. We're looking to add another Siamese for him to play with. The kitten would more than likely be his niece or nephew by blood (his breeder has two litters currently). My Siamese is okay with being in a multipet household, though he is most dominant. He only stands down to one of my ferrets and ignores another. The third he bats at (she interestingly enough helped "raise" him when we got him). He plays with my dog, but my dog is very submissive, and my cat takes advantage of that. However, he is extremely distraught if we leave with the dog, especially overnight, even though the pet sitter stops by to care for him.

My question is, given the details or not taking them into account, whichever works, does anyone have advice on how to make introductions as smooth as possible between him and the kitten. If they don't become friends, I don't know what to do. My cat is going to be heartbroken and confused if left alone once my dog passes away, and at 14, time is precious.
