As the consummate computer geek, you can bet I have a ton of wires dangling behind my desk. Before I got the cats, I bought a wire loom and put some wires through it, but I have so many wires, that I can't protect them all with looms and the pepper-flavored spray I tried didn't work. They aren't chewing them much, but it bothers me to see them climbing all over the power strips and cords.
About.com's Franny Syufy has a review of the Ssscat, a sensor which sprays cats with citrus and makes noise when they go to the wrong place. Maybe I should put one behind my computers. Any other suggestions? Please share.
