**1. Understand the source of aggression**

Aggressive behavior of kittens is mostly caused by fear or overexcitement. Noise in a new environment, unfamiliar smells, and forced hugging may trigger defense mechanisms. Observe body language such as ruffled fur and airplane ears, and evacuate the stimulus source in time. Avoid corporal punishment to aggravate hostility.

**2. Establish a positive interaction model**

Reward quietness with snacks and gradually shorten the feeding distance. Interact with a cat teaser for 15 minutes every day to release hunting instincts. Stay still when warned by a breath, and use toys to divert attention after it calms down, forming a conditioned reflex of "calm = attention".

**3. Set up a safe retreat space**

Provide a cat bed or cardboard box with a roof during the grumpy period to create a visual barrier. Place a pheromone diffuser in the conflict area (such as the combing area) to relieve anxiety. Wrap the nails with a towel to form a "cat curl" to avoid violent resistance caused by bare-handed control.

**4. Medical screening cannot be ignored**

Continuous aggression may hide painful diseases (such as arthritis and dental disease). If accompanied by excessive licking and hiding behavior, skin allergies or urinary system problems should be checked. If the attack frequency suddenly increases, it is recommended to cooperate with the veterinarian for behavior correction training.
