I'm really annoyed!

I went to pee and when I got back there was a message on my screen that said there had been a power surge on a USB device. I was instructed to click on the message "balloon" for more details. When I tried, I saw that the damn cat had chewed thru the mouse wire. For the third time! I immediately kicked him out of the room, along with his brother, and walked to Staples to buy a new mouse. Very annoyed, I've now spent $75 on mouses for this damn computer. A friend has suggested putting duct tape on the mouse wire. I feel more like putting duct tape on the cat's mouth.
