Most aggressive behaviors in cats are caused by emotional stimuli, so owners should avoid anything that might affect the cat’s emotions. If a cat shows aggressive behavior, how should the owner train it?

　　1. If it is a lonely old cat, consider adding a kitten companion. Because the old and young are more likely to accept each other, but pay attention that the kitten should be brought home by someone the old cat never knows. This person’s appearance aims to prevent the old cat from associating you with the kitten and feeling jealousy.

　　2. If the old cat is hostile toward the kitten, try calling the kitten "the old cat’s kitten," as this can create positive associations between them. Also, when talking to the kitten, speak to the old cat at the same time to engage the old cat and allow normal contact with the kitten, thus cultivating their relationship.

　　3. If the cat is particularly nervous around someone, try saying that this person belongs to the cat, such as "This is Lily’s cat, and it is Lily’s cat." This links them together. This will dispel the cat’s nervousness and anxiety toward that person, but repeated practice is necessary.

　　4. Cats are easily influenced by their owner’s emotions. As the owner, you should do more stress-reducing exercises and activities to help both you and your cat relax.

　　5. Some owners go to the veterinary hospital to use sedatives to control the cat’s emotions, but merely trying sedatives is a symptomatic treatment; to be effective, cat behavior must be rebuilt along with sedatives. Only this way can you help the cat reduce triggers of aggressive behavior.

　　6. Music also has a relaxing effect on cats and can reduce their aggressive behavior. So, you can play your music combined with gentle background music, which also soothes the cat.

　　7. When cats feel nervous, they naturally use their claws to attack their enemies, so you should regularly trim your cat’s nails. When trimming, it’s best if another person holds the cat to distract its attention.
