The first harsh reality that you need to look at when you're getting ready to prepare your home properly is the reality that a kitten may not be the right fit for your family. If you have a dog, you need to make sure that he is okay with kittens and cats being around. If you're not sure how to do that, there are a few ways that you can go about doing it.
In this option, you can simply put your dog near a cat, typically one that is owned by a friend of the family who is okay with it. See how your dog reacts to the cat and make sure there's no aggressive behavior. Some bad thing to watch for include chasing, (aggressively, not in a curious sense), growling or snarling, lunging or any other kind of negative behavior toward the cat. The dog should be curious and interested but not aggressive towards this cat.
Take note that a dog is going to act differently on his own turf than in someone else's turf, so if you bring a kitten home and you see this aggressive behavior (even though he was fine before), you are going to have to re-home the kitten for his or her own safety.
For this option go to a pet behaviorist (specific to your dog's breed) and see how the expert feels about the possible interaction between cats and dog specific to the breed as well as the actual personality and temperament of the dog itself. The thing about this is that you'll be getting a much clearer of an idea through someone who knows dog breeds and interactions between
animals. The reality is that you are better safe than sorry!
When it comes to another cat, you have to take the same precautions, especially in the sense of turf. Cats are independent and might not take well to having a kitten come into their turf, so in the sense of getting along, you must make sure that you introduce them properly
