cat game ???
        gems
        diff kinds of cats, and food

	swap cat with food = cat chomps food.  minor points for food vanish.
                food:  dry food
                food:  wet food
                food:  cheese
                food:  ham

	cat gets fatter ?

        line of diff cats = cat parade.  medium points.
        line of same cats = big points!
        line of cats with goat at the end = get rid of lots!

	any parade gives you more moves.


	game params:
		# of moves limit
		score
