I tried the plastic tube things from Home Depot/Lowes but still needed more control. I went on line and bought a couple packages of Cable Tamers, I think that is what they are called. They come with plastic ties, twisties, and the plastic tube things. It really controlled my cord clutter and kept Gracie out of it. I use the tube thingys for things like lamp cords. I use the cord tamers for my stereo cords/wires, home theatre, etc. If I cant tame it or cover it, I use gel deodorant on it. Gracie can't stand that stuff. Good luck!
Here is one at Amazon.com. You can also get them at Office Depot
