Love cats? You’re not alone! According to the American Veterinary Medical Association, cats are among the most popular pets in the world. In fact, more than 26% of households have cats in the United States alone.1 And for good reason: They’re adorable, affectionate, and provide great entertainment.

If you’re considering adding a cat to your family, here are a few things to keep in mind. Cats are known for their playful and affectionate nature, but some breeds are more aggressive than others. There is no one meanest cat breed out there as each one has its own personality and temperament. However, without careful socialization, some breeds are known for being more assertive than others.

That said, not all cats of a certain breed will be hostile or violent. In fact, most will be quite friendly. Many of the breeds known for being mean or aggressive are also known for being some of the smartest. Learn about each of the 13 meanest and most aggressive cat breeds below.

The 13 Meanest & Most Aggressive Cat Breeds:

1. Siamese

The Siamese breed is known for being quite a sassy cat breed. Siamese cats require a lot of attention and love. They can be quite demanding, which can lead to behavioral problems if they are not given enough consideration. Siamese cats are typically known for their high levels of energy and oftentimes playful personalities.

Siamese cats also have a strong hunting instinct and will often stalk and capture prey like birds and rodents. They can also be quite aggressive when disturbed or provoked, which is why they may not be the best choice for households with rambunctious small children or other boisterous pets.

Sphynx cats are known for being one of the toughest and crankiest cat breeds. This is largely due to the fact that they are known for being very independent and aloof animals, and can be quite territorial when it comes to their home and family.

5. Bombay

While all cats can be aggressive at times, Bombay cats are often noted for their particularly feisty temperaments. This is likely due to their hunting instincts—as they were bred to be mousers in India they have a strong drive to kill prey. Their aggressive behavior can include hissing, growling, and even biting.

This may be due to their high prey drive and as a result, they may not be the best choice for households with small children or other pets. Bombay cats are typically loving pets, and their aggression may be exhibited as a result of fear, frustration, or territoriality.

In some cases, a Bengal cat may also become territorial if there are other pets in the home, leading to skirmishes and fights.

7. Egyptian Mau

What Traits Do More Mean & Aggressive Cat Breeds Have in Common?

More aggressive cat breeds share a few traits in common. Firstly, they are usually more active and playful than other breeds. Secondly, they may be more territorial and protective of their space and family members. Finally, they are often less tolerant of other animals or people and might be more likely to attack if they feel threatened.

Many aggressive cat breeds share certain genetic traits, including a propensity for dominant behavior and a high prey drive. These cats may also be more resistant to pain and fear, making them more likely to attack other animals or people. It’s no coincidence that many of the cats we’ve listed above have a more recent “wild” lineage—breeds like the Serval, Savannah, and Pixie Bob are all bred from ancestors who needed to be tough to survive in the wild. If they are occasionally feisty, well, it’s only in their natures!

What Provokes Aggression in Cats?

Aggression in cats can be provoked by a variety of stimuli, including fear, anger, frustration, or territoriality. Cats may exhibit aggressive behaviors such as hissing, swatting, and biting when they feel uncomfortable or threatened. In some cases, cats may simply be responding to redirected aggression from another animal or person in the household. Environmental factors such as exposure to loud noises or sudden movements may also contribute to aggressive behavior.

Cats that are not spayed or neutered are also more likely to exhibit aggressive tendencies, as are those that have not been socialized properly. Female cats may also be more aggressive than males when they are protecting their kittens. It is important to be aware of these potential triggers and to take steps to avoid them or to manage the situation if they arise.

How Can I Prevent My Cat From Becoming Aggressive?

There are a few things that you can do in order to help prevent your cat from being aggressive. One of the most important things is to make sure that they are well-socialized when they are young, which will help them to be more comfortable around other people and animals. Kittens that are not exposed to human contact between the ages of 3 and 8 weeks are more likely to go feral. You can also try to create a positive association with handling and petting by providing lots of positive reinforcement through treats whenever your cat allows themselves to be touched.

How Can I Calm My Aggressive Cat?

In order to help calm a cat that is acting aggressively, try and determine what might be causing the behavior. For example, if the cat is aggressive around other animals or people, it might be because it feels threatened and is trying to protect its territory. In this case, providing the cat with a space of its own where it feels safe might help.


It is important to understand that not all cats are sweet and cuddly. Some cat breeds can be quite aggressive and mean. If you are considering adopting a cat, it is important to be aware of this and choose a cat breed that will be a good fit for your personality and lifestyle. If you already have a cat, it is important to make sure that your cat is getting the proper attention and exercise, or else you may experience their dark side!.
