(I forgot to add something)

I read somewhere that when they're kittens and they bite too hard when they're nursing, the momma will make a low growl at them to let them know it's too hard. So me and my husband decided that when Josie has her teeth digging into our skin, we lean down to her and make a low growling noise (with mouths closed) and she quits EVERY TIME!!!

It's something you should try if you have a truly aggressive kitty! Much better than yelling at her or anything else. It's almost as if she understands what that means.
