Genetic Flaw Leaves Felines Without Sweet Tooth

From CNN.com

I am by no means qualified to dispute research done by professional scientists, but as a parent of four cats, I have observed that the felines in my family have an affinity for Redi-Whip® that they do not have for other dairy products or other foods intended for humans. Since Redi-Whip® is probably the sweetest food product that my cats have ever tasted and is also their treat of choice, I can only conclude (albeit unscientifically) that the sugar has something to do with it.
