How to deactivate a Cat safely

Okay, let me simplify this, they have some lose skin on the back of their neck called a scruff, mother cats carry them like this by gently holding it with their jaw, they usually freeze up so their mother could easily carry them, it is a psychological thing, dogs also do this. But you should not hold an adult cat with just their scruff, they like to be petted on the scruff, but don't hold them with just the scruff, since their body weight is too high and it makes them uncomfortable, also don't grab them by the scruff if the cat isn't friendly to you, since sometimes dogs and cats grab each other by the scruff to dominate each other.
