Are Maine Coon Cats Aggressive?

Many potential Maine Coon owners might be nervous to adopt one of these giant cats. After all, nobody wants to be bitten by such a large animal!

Maine Coon cats are incredibly popular for a reason, though.

The Maine Coon temperament is one of their greatest attributes.

Most Maine Coons are so sweet and affectionate that they’ve earned themselves the nickname “the gentle giants of the cat world.”

In general, Maine Coons are not aggressive. However, every rule has its exceptions, and some Maine Coons can exhibit aggressive traits.

If a Maine Coon is behaving aggressively, though, it is almost certainly due to an underlying condition.

Stress, poor socialization, and even illness or injury can cause a Maine Coon to become aggressive.

Types Of Maine Coon Aggression

Cats can exhibit aggression in a variety of ways.

Here are the aggressive behaviors that a Maine Coon can engage in.

  • Biting
  • Growling
  • Hissing
  • Scratching
  • Lashing with paws
  • Fighting

Causes Of Maine Coon Aggression

Cats are complicated creatures. If your Maine Coon is behaving aggressively, there are a lot of possible reasons why it is acting that way.

Here are the 16 reasons why a Maine Coon might become aggressive:

1. Lack Of Socialization

If your kitten was not properly socialized with other humans, it will likely behave aggressively as an adult.

Unsocialized kittens will perceive humans as a threat and be wary and aggressive.

2. Hormones

Sex hormones such as testosterone can lead to increased aggression in cats.

Hormonal aggression is most likely to occur in cats that have not been spayed or neutered (source 1).

3. Feeling Threatened

Your cat may be acting in self-defense.

If it perceives itself to be threatened, your Maine Coon will naturally defend itself through any means possible.

4. Overstimulation

Just like humans, cats can become annoyed with too much interaction.

Many owners will find that if they play with their cat too much at once, their cat becomes aggressive for a short period of time.

5. Boredom

Maine Coons can also be understimulated. This breed in particular is highly intelligent, and they need lots of toys and enrichment to be satisfied.

A Maine Coon that is not receiving enough enrichment or attention might lash out with aggressive behavior.

A great way to alleviate your Maine Coons boredom is by buying them a selection of cat toys, which help stimulate their senses.

These are my top 5 favorite Maine Coon cat toys.

6. Loneliness

If a Maine Coon is not receiving enough attention from its family members, it could become aggressive out of sheer loneliness.

Those of you who suspect that your cat might be lonely, should immediately either change your schedule to give your cat more attention or consider adopting a new playmate.

7. Feeling Territorial

Cats are more likely to exhibit territorial behaviors if they are not spayed or neutered.

If your cat is frequently howling and marking its territory by spraying, this is likely the reason your cat is behaving aggressively.

8. Stress

Cats will often behave aggressively if they are stressed.

If your Maine Coon feels unsafe or is upset by many changes in its environment, it will likely become stressed.

9. Other Pets

Your cat might become aggressive towards a new pet if they are not properly socialized.

There is a chance that your Maine Coon perceives a new dog or cat as a threat to their safety or territory, and becomes aggressive as a result.

Owners should note, however, that in general, the Maine Coon cat breed has a reputation for getting on well with other household pets.

10. Family Tensions

Maine Coons are highly empathetic cats that are sensitive to the moods of their family members.

They might even become aggressive during an argument, or if they sense tension within the home.

11. Maternal Instincts

Are Maine Coon cats aggressive? If your Maine Coon has just given birth to kittens, then the answer is YES!

Some cats become more aggressive as a means of defending their young.

12. Disrespected Boundaries

We all love playing and cuddling with our cats, but it’s important to keep in mind that the feeling should go both ways.

A cat that feels its boundaries are not being respected might become annoyed enough to lash out.

13. Adversity To Change

Cats love routine. Big changes, such as moving to a new house or bringing home a new baby can cause a cat to react with aggression.

Even small changes can cause a cat to become upset.

Some owners have even reported that changing perfumes or laundry detergent has caused their cats to go crazy! (source 1).

14. Redirected Aggression

Sometimes, a Maine Coon cat might react aggressively towards an owner due to an external source that your cat can’t get at.

For example, a rather common occurrence is when a cat is agitated by another cat or human outside a window.

If your cat cannot attack whatever stimuli are outside, it might redirect this aggression toward anyone nearby (source 1).

15. Pain

An injured cat will instinctually attempt to defend itself from anyone and anything to protect its body while recovering.

If your cat is wounded or in pain, it might shrink away from you and even lash out.

16. Health Issues

Underlying health issues, such as urinary tract infections, stomach aches, and parasites can all cause a cat to act more aggressively.

Not all Maine Coon health problems are easy to spot though, so make sure you read up on the key signals to watch out for.

These are the ‘Top 7 Maine Coon Health Problems‘.

Maine Coon Aggressive Body Language Clues

Maine Coons may not be able to talk like humans, but they can give off very strong signals through body language.

So, you might ask, are Maine Coon cats aggressive? Well, if a cat is close to acting aggressively, it will likely assume either an offensive or a defensive posture.

Here are some Maine Coon aggressive body language signals to watch out for, in both kinds of posturing (source 1):

a) Offensive Posture

  • Constricted pupils: An offensive cat’s pupils will be constricted, meaning they are much smaller than usual.
  • Piloerection: Piloerection is when the fur on a cat’s shoulders, back, and sometimes tail is raised.
  • Stiffened Tail: The cat’s tail will be stiff, and either lowered or pointed straight down.
  • Aggressive Sounds: An offensive cat might, growl, yowl, hiss, or spit.
  • Legs: The rear legs of an offensive cat will be stiffened, with the cat’s haunches raised upwards.
  • Direct Stare: An offensive cat will likely stare directly at whoever it wishes to attack, and might even advance.
  • Ears: An offensive cat’s ears will be pointed upwards, with the backs rotated forward slightly.

b) Defensive Posture

  • Piloerection: Piloerection is when the fur on a cat’s shoulders, back, and sometimes tail is raised.
  • Aggressive Sounds: A defensive cat will likely hiss or spit.
  • Crouched Down: Unlike an offensive cat, a defensive cat will assume a crouching position, with its head tucked in close to its body.
  • Tail: Many cats will curl their tails around their bodies if they are feeling defensive.
  • Pupils Dilated: A defensive cat’s pupils will be either fully or partially enlarged.
  • Lashing Out: If a cat is feeling threatened, it might lash out quickly with one or both of its front paws.

Why Does My Maine Coon Attack Me?

Has your Maine Coon been leaping and attacking you? If so, it’s no wonder you’re trying to establish are Maine Coon cats aggressive!

There are two possible explanations for Maine Coon attack behavior:

1) Your cat is exhibiting a playful behavior

2) Your Maine Coon is attacking you out of aggression


Maine Coons are very playful cats, and in most cases, it is likely simply trying to play.

Kittens will play fight with their littermates when they are young, and this behavior is especially common in younger cats.

Acting Aggressively

Determining whether your cat is truly attacking versus playing can be tricky.

If your cat is truly acting aggressively, it will likely be exhibiting some of the aggressive postures listed in the above section.

If your cat is attacking you in an aggressive manner, it is unlikely it is doing so for no reason. A Maine Coon will not attack unless it feels it has been provoked (source 1).

How To Discipline A Maine Coon Cat

If you are facing Maine Coon behavioral problems, here are the best ways to train and discipline your cat (source 1,2).

a) Ignore Bad Behavior

If your cat begins biting or playing too roughly, stop engaging in the behavior straight away.

Your Maine Coon will eventually learn that it won’t get any attention by behaving that way.

b) Reinforce Good Behavior

Cats learn best through positive interaction.

If your cat is playing gently, give it a treat and maybe some scratches behind the ear.

c) Redirect

Redirect aggressive behaviors towards inanimate objects, such as a scratching post or a new toy.

Your cat will learn to expel its energy in a healthy way that doesn’t hurt you.

d) Consider The Environment

You can’t always blame a Maine Coon’s behavior on the cat itself. Sometimes, you have to make changes to your cat’s environment, even if that means correcting your own behavior!

If you regularly overstimulate your cat or cross its boundaries, then it’s no wonder your cat is behaving aggressively.

Remove stressors from your cat’s environment that might be causing aggressive behavior.

Are Neutered Cats Less Aggressive?

Maine Coons that have not been spayed or neutered may be more likely to exhibit aggressive behaviors. As a result, in many cases, neutered cats are less likely to be aggressive.

Neutering a cat will often reduce or eliminate sexual aggression and territoriality.

However, keep in mind that a neutered cat can still be aggressive, particularly if there are other underlying causes.

It is important that owners neuter their Maine Coon kitten at the correct time.

Maine Coon Kitten Behavior Problems

Most kittens will learn to play gently with their littermates.

If they bite or scratch too roughly, a sharp cry will tell the kitten that they were a little overzealous. This is how a kitten will learn to control its strength.

If a kitten is removed from its littermates too early, it might not learn to behave gently.

Also, if you teach your kitten to play roughly, it will retain its behavior into adulthood. It may be adorable when your little kitten bats and bites and claws at your hand, but will it be just as cute when your little lion is fully grown? Probably not!

The best way to prevent a cat from playing too roughly as an adult is to discourage rough play when it is still young (source 1).

Maine Coon Cross Kitten Temperament

A Maine Coon mix will likely exhibit many of the personality traits of a Maine Coon, meaning it is likely to be gentle and affectionate.

However, it may also receive some of the personality traits of whatever breed it has been crossed with.


  • A Maine Coon mixed with a Ragdoll is likely to be one of the gentlest, most even-tempered cats around.
  • However, if your kitten is a cross between a Maine Coon and a Siamese, the Maine Coon kitten may exhibit some of the more aggressive and temperamental traits of the latter (sources 1).

Why Does My Maine Coon Hiss At Me?

Cats can’t use words to communicate as humans do. Instead, they use other sounds and kinds of body language.

Hissing is a cat’s way of saying “Back off!” If your cat is hissing at you, it feels threatened, or it simply doesn’t want to be interacted with.

If your Maine Coon hisses at you, back away and give your cat the space it needs (source 1).

Are Maine Coon Cats Moody?

Maine Coon cats are not usually moody.

They are generally recognized as being one of the sweetest and most even-tempered cat breeds.

If your cat is acting moody, it is likely a result of stress or an underlying health condition.

Why Does My Maine Coon Growl?

Growling, like hissing, is another way for cats to communicate that they are upset, frightened, or threatened.

If your cat is growling, leave it be and give it plenty of space (source 1).

Why Does My Maine Coon Bite Me?

There are three different reasons why cats bite, and they all mean wildly different things.

1. Aggressive Biting

This kind of biting is usually the most painful!

A cat will bite aggressively if it is angry, scared, or stressed. You can usually tell that your cat is biting you for this reason if its posture is aggressive.

2. Playful Biting

Cats sometimes bite when they are playful. This is not done out of anger, and it is not usually painful.

If your cat becomes too rough, gently redirect it or ignore it until the behavior stops.

3. Love Bites

This gentle form of biting is one of the unique ways a cat displays affection.

If you are petting or cuddling your cat, it might give you a gentle nibble as a show of love (source 1).

Maine Coon Cat Attacks Family

If your Maine Coon is attacking you and your family members, you must first assess if your cat is acting playfully or aggressively.

Note whether your cat is displaying an aggressive posture.

If your cat is attacking you playfully, but it is acting too roughly, discourage the behavior by redirecting your cat’s energy to its toys, or by ignoring the behavior.

If your cat is attacking out of aggression, assess the possible reasons why. Is your cat feeling stressed, jealous, or threatened? Or is your cat sick or in pain?

Cats rarely attack without reason. If you can discover and fix the cause behind your cat’s behavior, you will be able to prevent future attacks.

Here is a playful example, of a Maine Coon attacking his family in a Youtube Video by Youtube channel – Julia F.

Do Maine Coons Get Jealous?

Maine Coons are fiercely loving towards their humans, so it should come as no surprise to learn that they can become jealous.

If a new cat, dog, or even baby is introduced to the family, your Maine Coon may feel betrayed if it receives less attention.

Although unlikely, your Maine Coon might behave aggressively towards you or the new addition as a result (source 1).

However, more likely than not, your Maine Coon will be just fine as they are one of few cat breeds that like companionship, and the company of other household pets.
