CATDOLL : Why can't you pinch a cat's back?

The main reason why a cat's back cannot be pinched is because the area between the cat's back and neck is its sensitive area. This area is also one of the cat's weapons, and strong stimulation may cause a painful reaction.

There are many sensitive nerve endings on the cat's spine, and when it feels strong stimulation, it will produce a pain reaction. In addition, this part is also one of the cat's weapons. In the wild, when a cat feels threatened, it will arch its body and stand up the hair on its back, which can make it look more majestic and make itself look bigger, thus scaring away the enemy.
