Owls are supposed to be able to see in very low light levels. This one must have had something wrong with it. It probably would have died of starvation anyway due to not being able to hunt. It’s kinder this way.
Either every single Pepe le Pew cartoon was the same, or I’ve just been seeing the same episode over and over and over. There was always some white paint that got knocked over onto the poor cat. Also; I’m pretty sure he was in the French Foreign Legion for every episode. That might be my memory playing tricks.
