the darkness has not overcome it

Luther the ferocious and mighty bathtub hunter! I wish you had a pic. of him with the box on his head. His destiny. Actually, I think it is a great idea. Knowing you as I do, I know how motivated toward cat health you had to be before deciding to purchase sacrificial mice. I am sure you delighted Luther with this opportunity to do what cats do. What a treat. (your description of the whole event too.)
