There is an old saying about cats and (pardon my bringing the great furry oafs into this discussion) dogs:

If you bring a dog in out of the cold, give it shelter and food, and a warm place to sleep, it thinks you're God.

However, if you bring a cat in out of the cold, give it shelter and food, and a warm place to sleep, it thinks it's God.

That pretty much sums up cats, IMHO.
