I too have had dogs and cats all my life.............
IME, my cats territory is usually upstairs when we have puppies and adolescent dogs, they prefer to move out of the way......... the problem is young dogs love to play, love to chase, bounce, nip and make noise, for adult cats, it is annoying and potentially dangerous, more so to a pup or young dog who may get a nasty swipe, puppy eyes particularly need protecting.
Whilst your pup is young, allow your cats to do as they please, keeping out of the way may be what some of them will continue to do, others may teach the pup a lesson or two, they find their way, just allow things to progress naturally.
You will see a difference as your pup matures. With all adult dogs in and visiting my home now, my cats will sit on the sofas next to them, eat and drink in the same room, in fact my eldest cat no longer even sleeps on my bed, prefering to stay with the dogs. They have grown extremely close, but for years he avoided all dogs.

Other cats are fine from the first few days, some will take longer, some even longer...........but all your animals will still be a part of your home, no matter which room they are in, so don't worry............they don't need to all be in the same place to feel loved.
