That’s the Way to Make the Cookie Crumble
Rats do not have very good eyesight—especially PEWs (Pink-Eyed Whites), which can hardly see at all. But they are very good at judging distances. If a rat urgently needs to get from Point A to Point B, and there is a yawning chasm in between, it will figure out how to get there comfortably.
In another fine case of Life Imitating Art, the rats took this image to heart. After I barred them from their previous favorite hideaway inside a wall, they looked around and finally settled on a bookcase next to the aquarium. I didn’t understand the attraction until bits of paper started accumulating on the floor. Fortunately, the selected book—a single-volume encyclopedia—wasn’t one I use often, or one that needs to remain in pristine condition.
Even more fortunately, they never developed a taste for aquarium cords. This particular one didn’t have a GFCI.
Just ask St. Cassian, patron saint of teachers, whose students stabbed him to death with their pens.
