Summarize this article:

Your home environment may have a lot of obstacles and conditions the cat either may adapt after several months or years, or not at all. Some obstacles that are typically more difficult to overcome are young children and existing pets, especially dogs. High levels of patience are required and it helps if you are able to provide a dedicated room for the cat the first few months. This helps the cat adjust to new territory and will likely pay off in the end by establishing a warm relationship.
Help your cat adapt to the new home environment. Provide lots of encouragement for the cat.
