A cat's fur may be caused by anger or fear. When a cat's fur explodes, you must stabilize the cat's mood and avoid irritating the cat to avoid aggressive behavior or stress reactions. You can use toys, cans, cat strips, freeze-drying, cat teasing sticks, etc. to distract the cat's attention and relax the cat. If the cat still has hairy hair, it is best to let the cat stay quietly for a while.
