The best way to keep a cat from scratching and biting

When a cat gets too aggressive, I have found if you hold the cat down by scruffing and holding the cat down until she calms down. I have observed mother cats doing that to kittens. I have a high strung female who gets mean and harrases her two brothers and I.
I found that this works. I learned this from observing the mothers and kittens I have fostered.
