I've never gotten the impression an animal was aware it could change me. Sure it'd make its wants clear until it got what it wanted or got bored, but that's a very primitive form of conduct. The cat clearly knows I can get it more foods between meals. The communication is limited, but I've never seen him come up with a better argument than that he really really wants more food. Dogs are stranger and clearly has a concept of social structure that cats don't. Both from their background as pack animals and deliberate domestication for assisting humans in work.
