First, check all cords to make sure there have been no breaks in the integrity of the insulation. If any spot seems chewed or frayed, replace the entire cord immediately.
Reduce temptation by securing cords to table legs and baseboards. You can find electrical cord covers at your local home improvement store that attach to baseboards. You can also bundle computer cords inside a PVC pipe. Cut a lengthwise slit in the pipe and squeeze the cords through.
All cords that you can't secure should be coated with a bitter anti-chew preparation, available at pet supply stores. Use disposable gloves when applying it, because it truly does taste bitter!
