Aggression in cats can be triggered by a variety of external factors. It often occurs so unexpectedly that the owner doesn't have time to notice the cause. If you notice your cat exhibiting this behavior, you should try to moderate it to prevent it from escalating into aggressive behavior. To ease the process, follow these steps.
Get down to her level
Sit calmly next to the cat, avoiding any sudden movements. This will let it know you pose no threat. Don't touch it, as this could lead to an attack.
Let her come closer to you, sniff you, and examine you. This will relieve her panic and likely relax her.
Distract with a bag of food
Distractions always work, especially when it comes to food. Play with the food bag to stop her fixation on her anger. She might just snap out of it and want a snack.
Don't tease her under any circumstances: if you show her the bag, don't hide the treat. Instead of a treat, you can attract her attention with her favorite toy.
Do not hit
Responding to aggression with aggression is not the answer. Using physical force will only further confuse you, as your cat may become so enraged that its mental state will need to be addressed by a veterinarian. Beating it will only lead to further fear, and such outbursts will be repeated.
If your cat is at its limit, avoid punishment, no matter how it behaves. In severe cases, it's best to leave it alone in a separate room.
Avoid direct eye contact
Eye contact is interpreted as a challenge by the animal. An enraged cat, taking this cue from you, will attack you. When sitting next to it, look away so it doesn't see you as an obvious threat.
The best way would be to ignore it completely.
Spray with water from a spray bottle
If all else fails, the cat will prepare to attack. Since hitting or running away is pointless and will only make matters worse, use a water sprinkler.
This is an extreme measure, and should only be used occasionally. Cats are afraid of water, so this will let her know that her behavior is wrong. Eventually, she'll calm down completely.
Seek qualified, professional help if you feel you can't cope on your own. Start with a visit to the veterinarian.
