My cat also likes to chew on cables. She started as a kitten, she is now 6 years old and still does it, though not as much,(the vet said she was teething), and has cost me 2 answering machines and a lamp. I have noticed she does this most often when nervous, even though there is another cat in the household to play with. Wrapping cords in BLACK electrical tape does stop them, they don't like the taste. Also for computer cables and such, go to the hardware store and get the thick black covers for cables, not the cheap clear/thin ones you can buy at the computer store for "organizing your cables". The black electrical tape works the best, though it is time consuming. Do NOT use other colors, they are flavored differently. Hope this helps.
