Thanks to all of the wonderful listeners who called or emailed with suggestion for me to stop my kittens, Finn & Flora, to stop chewing on cords and climbing our Christmas tree!  ~Murphy

Some of your suggestions:

Bitter apple spray for cords

Wrapping cords in aluminum foil

Putting crumpled newspaper or aluminum foil under the tree

Shaking a can full of pennies at them when they try to climb the tree

...and many others!
