Much cat behaviour is consistent across the breeds.

Cats are territorial. This means, if you accept them into your house, they will regard it as home. They do “spray” to mark their territory, this is to scent-mark and is normally confined to un-neutered males. But their usual means of making themselves “at home” is to scent-mark by rubbing their flanks and faces against objects. This doubles as a sign of affection and the scent is not obnoxious or particularly noticeable to human beings.

If you want to communicate, learn the cat’s body language and speech.

He can often understand your language, but has difficulty “talking” it. This does not mean he won’t try. I have known several cats who did master a few words, though they have all tried long conversations on occasion, especially when they have something terribly unjust to tell you about. The cat kisses by touching his nose to yours, but he is loath to do this till you have shown your friendship by rubbing your cheek against his. He will reciprocate by rubbing his cheek or the top of his head against you. Another sign of affection is the slow blink. To get your attention, he may reach out and touch you with a forepaw. Wikipedia has an excellent article on cat behaviour, including body language and “speech”.
