Welcome, Crazy Cat People!

The Siamese cat is an ancient cat from Thailand with a very spiritual history. Before adopting a Siamese it’s normal to have numerous questions, one of them being ”Are Siamese cats mean or aggressive?”

I used my knowledge of this breed and cats, in general, to answer your questions below.

As a general rule, Siamese cats are friendly and affectionate and not mean; however, some Siamese can have tendencies to be stubborn, dominant and possessive. They have high energy levels so need lots of interaction, and regular play and behavioural issues may arise if their basic needs are not met.

Later in this post, we go into the subject in a little more detail, we also examine if Siamese cats bite and also what you can do if your cat is aggressive and the potential reasons why.

Are Siamese cats aggressive?

Siamese cats are known for their playful, friendly nature and their super high energy levels. They tend to pick a human in a household as their favourite who will become the centre of their little universe and they have a tendency to follow you around everywhere you go from room to room.

With a Siamese, it’s common to not be able to even go to the bathroom in peace! They thrive on human interaction and behavioural issues such as separation anxiety and depression may arise if they are neglected or left on their own for too long, according to Wikipedia.

They have a reputation of being one of the most vocal breeds of cats who will happily chat away all day long to humans and other animals. They generally get along with other pets quite well as long as they are introduced properly and slowly. They have an intelligent, inquisitive nature and can easily learn tricks that will keep them entertained for hours and will also keep their humans entertained with laughter. 🙂

Like all living beings though they have two sides to their personality and they can be very persistent and stubborn at times and are known to be a more territorial, dominant breed of cat. With a territorial nature and such a love for humans they occasionally experience jealousy but remember it’s only because they love you.

If a Siamese cat is aggressive then they are more likely to show this to other animals in the home and not humans. Any signs of dominant behaviour and aggression can normally be kept in check with regular exercise and enrichment of the home with toys and vertical places they can claim as their own but we will go into more detail with that later in this post.

We are Siamese if you please!

I always like to ask people their own experience with their cats to get a true idea of just how mean or friendly their cats can be so I did a Facebook poll when writing a similar blog post on the Siamese which you check out here.

I wanted to find out how many people said their Siamese cat was friendly and how many people said their cat had aggressive tendencies.

A whopping 90% said that their Siamese cat was friendly and good-natured so generally if you are thinking of adopting a friendly cat then you can’t go wrong with a Siamese.

Just be sure you have enough time on your hands to keep them entertained to avoid any potential behavioural issues such as aggression.

Why Do Siamese Cats Bite So Much?

So if you have a Siamese cat and they are biting you this can be for several reasons.

Let’s think about the Siamese cats personality for a moment, we already know that they are a very playful and active breed of cats with a lot of energy. Some owners say that this can give them a tendency to bite more than other breeds.

If your cat is just play-biting then it probably isn’t going to hurt, cats are not stupid and the Siamese cat is highly intelligent and shouldn’t give a nasty bite to its humans.

They are very territorial which means they will fight to protect what is theirs when they feel under threat by another person or animal in the home. So this could be when you may experience or see your Siamese cat bite.

Let’s have a look at some of the reasons why your Siamese cat may decide to bite.

  • Is she afraid? – Any changes in her environment, such as new people and even furniture, could stress your cat out and make her bite. Introduce changes slowly and the same goes for introducing other pets into the home.
  • Frustrated or uncomfortable – Sometimes your cat may just not be in the mood; they are allowed an off day every now and again, so learn to read the signs of when to back off and when they may want a bit of alone time.
  • Previous abuse or neglect – She may bite if she has had a history of abuse and neglect. If this is the case then it’s time to find out a little more about how you can gain the trust of your cat and I have the perfect resource for you! I made a whole blog post with 13 clever ways to build that much needed trust and you can read it by clicking on this link.
  • Too much play energy – Cats need to feel like they are hunting and stalking their prey and using up energy, especially the Siamese cat. So if they are biting you, it may be a sign that they have too much stored energy waiting to be used, so take out the toys and get playing.
  • Not being given enough attention – Siamese cats need attention and they will let you know about it in a multitude of ways if you don’t give them the time, love and cuddles that they crave, and one way they may do this is by giving you a little bite.
  • Overstimulated – Cats can sometimes become over-stimulated through play and stroking. Some signs to look out for are huge dilated pupils and a change in their vocalization. When your cat is in this mood, its best to leave them alone for a while and back off.

If your cat has suddenly started biting or is showing signs of aggression it is always best to seek veterinary advice as soon as possible to rule out any health issues. One of those issues could be a pain especially if your cat is biting you whilst you are stroking them so it’s important to get to the root cause of the issue.

Once you have gotten to the root cause and it’s not related to any existing conditions it’s then time to see what we can do about it.

What to do if my Siamese cat is aggressive?

So what do you do if your Siamese cat doesn’t fall into the standard Stereotype of being affectionate and they are acting aggressively towards you or another pet in the home?

A cat who is acting aggressively is acting that way for a reason and the worse thing you can do is create more stress by shouting, chastising and punishing your cat.

I know it can be frustrating but imagine how they feel? The behaviour problem could be worsened by making them feel more scared than they already do.

So let’s have a look at some of the reasons why they may be acting aggressively.

Territorial Aggression

This type of aggression can be common, Siamese cats are very territorial and they own their territory with pride and they will protect what is there’s.

This can occur when you are introducing two cats to each other so it’s important to follow the correct methods of introduction, this needs to be done slowly and over time with both cats in separate rooms. Always introduce through smell first before visual and remember first impressions count with cats!

To find out more about how to correctly introduce your cats, I recommend watching this video by the original cat daddy Jackson Galaxy.

If your cats already live together and they have begun to fight then it may just be a case of needing more items within the home for each cat.

So make sure there is a litter tray per cat if they are not used to sharing (See my post regarding if multiple cats can share a litter tray), make sure there are enough beds per cat and also enough feeding stations to reduce territorial aggression.

Playful Aggression

You will hear me go on so much about play energy and Siamese cats have a lot of energy to be used. They are very active and need regular play and if you don’t give them the stimulation they need they may be aggressive with other cats and they may also be mean to you.

It’s not their fault, it’s in their nature to be active and if your Siamese is an indoor cat you need to enrich their environment with lots of toys and make your house a palace for your cats. You can add superhighways which are shelves that run around your walls, you can also add more toys in general and make sure you spend at least 15 minutes twice a day engaging in interactive play.

This should use up some of that playful energy and help to prevent any fights in the home.

If you are out of the house a lot of the time or even if your not, I wrote a super helpful blog post with 13 tips and tricks to keep your cat entertained, this one is defiantly worth a read, click this link and find out more.

Overstimulated Aggression

Cats can get easily overexcited and overstimulated, there may be lots of noises, new people or maybe they are just in a highly stimulated state from a dose of catnip or a good play session.

Cats also become overstimulated from stroking them and touching them too much.

The way to deal with this is to know your cat, look out for the signs. Do they look happy being stroked? Do they look approachable? Are there pupils dilated? Over time you will learn to read these signals and when your cat is in this mood it’s a good idea to just give them a little space for a while.

Have the cats been neutered/spayed?

Male cats especially may be more aggressive and show more territorial behaviour when they have not been neutered. Male cats tend to fight more when not neutered with other male cats especially if there is a female around that is in season.

It’s your decision if you want your cat neutered or not but if you don’t want kittens it may be a good idea and can help to reduce any associated aggression.

There are also other things that you can try when your cat is being aggressive to reduce stress such as holistic therapies.

For those of you that are spiritually open-minded and interested in the healing energy of reiki then have a read through this post I wrote to find out more, it’s amazing for reducing stress levels in cats and helping to balance their energies so they can begin to heal themselves.

There are also other holistic therapies such as bach flower remedies for cats and other herbal products you can buy to help. So bring a little bit of Zen into your cats’ life, they will thank you for it.

Do Siamese cats like to be held?

As a general rule Siamese cats love to be held by their owners. They are an extremely affectionate breed and they thrive on close human companionship. Some compare the Siamese cat to a dog due to its loyal, loving and devoted nature towards humans and their need for regular affection.

They are one of the most affectionate breeds, so if you are looking for a cat who will enjoy cuddles and likes to curl up next to you while you watch TV then the siamese may just be the breed for you.

They do demand lots of attention so please make sure you can provide this for them, they give as good as they get when it comes to the love they give. It is possible to develop a really strong lasting bond with a siamese cat as long as you can keep up with their high energy levels.
