In most cases, anger is caused by fear, and aggressive behavior from the point of view of a cat is simple self-defense. If the animal is in conditions that cause him fear, aggression can not be avoided.
#1 Think about the reason the cat is angry.
The primary reason for showing anger or aggressive behavior in cats is fear. Cats are not as well domesticated as dogs, and easily return to show wild habits. That is, cats are just one step away from wild animals. Remember that the cause of fear may not always be immediately obvious to you. For example, your cat may begin to hiss at the baby who managed to pull his tail while you were not in the room. A cat can associate a child with pain and be afraid of him.
#2 First of all, take care of your own safety.
If your cat is angry with you or simply redirected aggression towards you, then you are the likely target of his attack, which can lead to scratches and bites. However, most cats are not likely to attack, unless people continue to provoke them after they have shown warning signs.
#3 Always have a spray bottle of water in your room.
Spraying an evil cat may be ideal if you do not want to endanger your hands. This may be sufficient to disperse the fighting cats and will serve as a good means of self-defense if the cat decides to attack you as a result of redirected aggression.
#4 Take a step back from the animal to reduce its fear.
#5 If possible, leave the room the cat is in. If the cat reacts to another person or to another animal, take them out of the room.
You should probably leave the cat alone for 10–20 minutes to allow him to calm down.
