When real things happen to imaginary people

I gave a mouse with a motion sensitive little chirpy noise in it from a imbedded micro chip to a friend's cat and it played and played and played with it. Then one day it decided to drown the little bugger and put it in it's water dish. After my friend found it there and rescued it, it sort of warbled in a warped record sort of way when played with. A week later where was the mouse but in the water dish again. Never to be heard from again. That finally did the electronics in the mouse in. The cat lost all interest in the mouse when it no longer made sounds when batted around. Odd cat.
