I am sure Korean scientists had some worthwhile goal in mind when they cloned a litter of beagles and made them glow red by inserting fluorescent genes into them.
But don't even get me started about using dogs in experiments. That is a dark place not made any brighter by glow-in-the-dark puppies. That the scientists chose red - a color not even seen by dogs - just makes it worse.
But I admit I felt a little grim satisfaction that they tried it on cats first. Heh.
