Anyone ever tried Bitter Yuck to hold on to their cat from chewing on something it shouldn't?

I have used Bitter Apple in the past when I have a Beagle. It was a good deterrent for him. My cat is chewing on the Christmas tree and I am afraid he will bite a light cord. I call the pet store and they said they sell a product from the makers of Bitter Apple called Bitter Yuck. Just wondering whether I should try it. I can't stand guard 24/7 with a squirt bottle of cold water. :-)
Answers:    yeah. i tried bitter yuck because my dog was chewing on the sofa. it works really well. after your cat tastes it i don't think it will be chewing on the tree anymore.
I haven't tried it but I've found a moment or two lemon juice or vinegar rubbed on the cords keeps mine from chewing them.
My cat is terrifically calm but have just this minute be biting me surrounded by my sleep, any aid?   My cat is not nursing her newborn kittens. What should I do?   Boots For Cats??   Why does my bengal cat other meow?
