If your kitten does something wrong, put 15 pennies in an aluminum can. Once you've done that, tape up the top so the can is closed and pennies can't fall out. Then, shake the can. The kitten will be afraid of the noise but your voice does not participate in this trick. Also, if your cat does a bad thing again, you should still do the same trick. But, do not try to hurt your kitten in any way.
