A change in personality and temperament. A cat may go berserk, bite and growl. It means you, as a cat owner, have renounced the responsibility you assumed when you fell in love with that kitten or cat.

Emotionally cats feel defenseless and thus live in a constant state of stress, making them more prone to disease. Despite its grace, a cat is not sure-footed. Without the lightning quick ability to grasp with its claws, it can easily be injured in a fall. It is fairly common for a declawed cat to become a biter. They do this out of fear and frustration.
