I don't really have any advice for you, but I would definitely make arrangements to keep them seperated until you know you can trust Tikeya with the kitten. I hope it works out. I worry about the same thing with our Bulldog, Mack, if we were to bring in another cat. We have no problems with him and our Butter, but Butter was here when Mack was a puppy, so he grew up with him. Good luck!! Kittens are so much fun!
