Why is My Cat Attacking Me All of a Sudden? And How To Handle
Cats have a bad image for being unpredictable due to their penchant for aggression and unpredictability. This might be really damaging. Sadly, cat aggression is a very common problem. Actually, it’s the second most popular excuse for bringing in a behavioural specialist.
If your cat suddenly attacks you, you’re probably also trying to figure out why is my cat attacking me all of a sudden. What specifically went wrong? However, this problem cannot be solved easily. Cats may act aggressively and attack their owners for a number of reasons! When you’ve read my analysis of each in this post, decide which you think applies. The first and most important step in stopping your cat’s attacks on you is determining what is causing them.

What Causes Cats to Attack their Owners Randomly?
1. Play Aggression
Cats are hunters by nature. Because hunting is a survival skill for wild cats, it is built into their DNA. They would practically starve to death if they didn’t hunt and acquire their next meal. The odds of survival increase with the level of the hunter.
Domestic cats still retain these hunting tendencies even if they don’t need to hunt since you feed them breakfast, noon, and supper without making them work for it. Play is one way to deal with this habit.
Encouragement of aggressive play is inappropriate since it ignores undesirable behaviour (not reinforcing it with your attention). If your cat attempts to play rough, get out of there, ideally into another room, close the door, and keep quiet. No reaction indicates that your cat does not receive attention for the undesirable behaviour (and as a result, they are less likely to do it if they realise they won’t receive attention for it).
In positive reinforcement training, “good” behaviour is also rewarded. Therefore, you may give the cat a food treat when they are playing with their cat toy or when they are comfortable and peaceful.

2. Territorial violence
Cats are ferociously territorial creatures who use scent to claim objects and areas as “theirs.” If their territory is in jeopardy, they will stop at nothing to preserve it. As a result, if your cat suddenly starts attacking you, it may be because they believe its territory is being invaded.
When a stranger or new animal enters your home, territorial aggression typically follows. Your cat dislikes suddenly having to share its space with this new creature since it is unfamiliar with it. Then, they frequently escalate their violence in an effort to defend what they perceive to be “theirs.”
3. Anxiety & Fear
Fear aggression is another common reason why cats suddenly attack their owners. Cats are extremely sensitive creatures that often become startled. Strange smells, loud noises, and schedule interruptions can all cause fear.
In response to fear, cats no longer snap and attack. They attempt to scare the threat away at first before running away. Sometimes, Cats will arch their backs to make themselves appear larger and more dominant. Additionally, they’ll look for a fast escape they can utilise in case things become physical.
Take action to prevent the trigger condition from happening, such as blocking window sill access, covering windows, or excluding other cats.
If the cat appears to be excited by something, don’t handle them.
It could be feasible to gradually desensitise the cat to the frightening stimuli, or you might adopt a counter-conditioning technique in which you reward the cat with food when they remain calm in the trigger setting. Rewarding a calm child with a goodie strengthens their ability to remain relaxed while being exposed to the horrific occurrence.
Additionally, medication may be used with behavioural adjustment (your vet will advise).
4. Health Issues
Every time my cat bites me without cause, I call my veterinarian. Unusual aggressive behaviour is commonly associated with medical conditions. These illnesses may cause your cat discomfort, which makes them irritable and irritated. These feelings could lead to aggression toward you and other individuals.
Cats are masters at hiding their pain. Again, this relates to survival since predators are more inclined to attack cats who appear sick, injured, or fragile in the wild. Cats have a better chance of surviving if they can conceal their discomfort and act as though nothing is wrong.
5. Previous Trauma
Oftentimes, cats with a history of trauma are more sensitive. They could exhibit aggressive behaviour more frequently than other cats and have too intense reactions. This typically results from anything that triggers heightened responses in them and terrible recollections of their event.
It’s very possible that your cat, which you recently acquired off the street, attacked you without reason. They are agitated mentally, which is why they act erratically and maybe aggressively. They can’t control their mental disease, which regrettably frequently manifests as rage.
6. Petting-Induced or Overstimulation Aggression
When I pet my cat, she will occasionally bite me. Petting-Induced aggression produced by petting is the term used to describe this form of antagonism. It is a result of overstimulation. When you give your cat a long, satisfying stroking, the joy and satisfaction morph into pain. Like most things in life, cats only sometimes like being touched.
Every cat has its own restrictions when it comes to cuddling. Some creatures are quite patient and will happily allow you to pet them for about 30 minutes. We must respect these limitations, no matter what they may be.
7. Redirect Aggression
Cats become aggressive when humans try to handle them after being aroused by things unrelated to them, such as chasing a pet or fighting another cat. A classic example of redirect aggression is i.e It is common for cats to display territorial aggression when they witness or smell an unwelcome cat. In this case, the cat directs aggression at another person within the household since it cannot directly interact with the outside cat.
Redirected aggression in cats can be triggered by any external stimulus, including seeing small prey outside the window.
Take action to prevent the trigger condition from happening, such as blocking window sill access, covering windows, or excluding other cats.

8. Noise-induced aggression
Certain sound frequencies have the potential to make cats aggressive. Examples include the howling of another cat, high-pitched whistling, a baby screaming, or squeaking sounds.
Avert trigger sound frequencies (where possible)
When it is acceptable and safe to do so, you can experiment with desensitisation and counter-conditioning. The “trigger” sound is played at a very low volume to desensitise a cat to noise. If the cat remains relaxed and comfortable, they are then rewarded with a delectable treat (counter-conditioning). The cat gets treats as long as they remain calm and quiet throughout the sound, which is then gradually raised.

9. Heat and Sexual Arousal
Finally, if your cat is in heat, it could attack you without warning. This results in a number of behavioural changes. While some females grow friendlier while they are in heat, some females become aggressive and attack their owners.
Males do not go into heat, yet when sexually aroused, they may still attack. When they detect a nearby female is in heat, males become fixated on finding and mating with her. Male cats have a tendency to grab the female and bite her during mating to keep her from escaping. Therefore, if your boyfriend notices an active girl around, it is common for him to bite you.
Recognise the warning signals of an aggressive sexual mount to stop it (e.g. leave the room).
So, distract the cat’s attention when this behaviour starts by giving it a toy or some food (food treats should not be given if the cat is already showing aggression as this may negatively reinforce the behaviour).
