Identify large grey bird with black head and green talons?

I went outside to find that my cats had killed a bird, but I've never seen a bird like this. (I'm in Fort Worth, Texas). The bird is football-sized (bigger than a pigeon) and grey with a black head. It has white under its tail. It's feet are a gorgeous nearly lime-green color with some blue. It has a triangle pointed beak (not curved) with a hole through the top. Does this sound familiar?

1. Need more details - can you describe what it is like? Is it similar (and in what ways) to any other bird you've seen? About how long is it? Does it have any other coloring on it? Is the coloring solid, splotchy, striped, etc? Are it's feet webbed? Toenails very sharp? Is it's beak shorter, same or longer than the head? Any special design on it's head? (ie stripe on eye or a crest...) Can you pull out it's wing and tell just what shape it is?
2. It sounds like an American Coot. http://en.wikipedia.org/wiki/File:Fulica_americana.jpg
