Keep the paper out of your cats way!!  What are you feeding your cat?  What kind of toys does your cat have to play with?  My cat shreds paper.  If you leave a piece on the floor, it will be turned into confetti in no time.  You need to watch out for pantyhose, tinsel, and many plants.  Give your cat cat grass.  You can buy it in almost every pet store on the planet.  Buy her catnip, which she can eat and enjoy.  Cosmic Catnip seems to be the best.  You need to replace the bad behavior with an acceptible one.  Praise her when she plays with a ball or a wand toy or the catnip and simply take the other things away.  You have to "cat proof" your home the same way a parent needs to childproof their home.  You have the larger brain.  Think like a cat.  Never hit a cat and never scream at your cat.  Cats act out in other ways when unhappy, so just learn what the cat enjoys eating that it shouldn't, and keep it away from them.
