How Much Hissing Is Normal When Introducing Cats?

Cats are one of the most adorable creatures on Earth, who are cute, sweet, and calm to keep.

They hunger for attention plus love and make all possible efforts to accomplish it to nurture their well-being.

If their part of warmth is moved to a new cat within the house, a reaction arises.

This type of response is known as hissing, and it is found to be a common behavior in cats.

This behavior expresses fear, not aggression or hatred towards cats, kittens, dogs, and even people.

The amount of hissing may vary depending on the situation.

The Reason Behind Hissing

Hissing is due to the sensitivity of being threatened, upset, or dreadful about a situation that the cats may encounter.

When a cat feels endangered, it shows certain cautionary signs in return. The sign can be of various types.

It can be an uncomfortable behavior, irregular living, or a reaction in the form of a swat or bite.

A cat may also hiss when she is a new mom and is defensive toward her kittens.

Mother cats are fiercely protective of their young.

When someone gets too close to them, whether it’s a person, another cat, or another animal, they hiss.

It may also be due to a situation in terms of a traumatic condition like moving to a new place.

The hissing can be due to the discomfort or pain that a cat may face.

Significance Of Handling Hissing

It shows that the first introduction between pets is as significant as that between people because it lasts forever.

A gradual tactic of introducing the cats to someone new can be helpful.

Most of them are unable to accept the change. Patience is the most important factor in creating a friendly environment among cats or a stranger.

There is no need to blast out, and all that is required is a focus on the steps with capability.

Cats Hissing In Various Contexts

Hissing is a form of communication that cats use to share their state of stress with their owner.

They may have some concerns with the new change or surroundings. A hiss will also change depending on the situation.

A hiss can be anything from a silent, open-mouth expression of unhappiness to an aggressive hiss that includes full-on spitting.

Cats act differently every time, depending on the type of opponents they may come across at that time.

As discussed, hissing is normal behavior, but the extent of it in various contexts is discussed below;

Cats Hissing Towards Cats Or Kittens

Cats are possessive when it comes to spaces in the home. 

If any other cat or a kitten tries to disturb their personal area, hissing may occur in that situation.

Cats usually hiss to show dominance because such a change is not acceptable to them.

Similarly, the cats may hit the kittens out of frustration in the form of a harmful swat or bite.

Ensure the safety of the kittens by keeping an eye on the behavior of the cats while they hiss.

Problems can be handled at an earlier stage if given serious attention before time.

Cat hissing when they see each other is just normal. 

If it continues for 2 minutes and shows signs of threats (swatting with force, chasing, screaming, ears flattened), you can always separate them.

When a cat interacts with a new cat, it may hiss for 1-2 minutes but take that hissing as normal.

It can also take a time span of seven days for a cat to hiss toward another cat or kitten.

The best way here is to create a barrier between the cats and kittens to become familiar.

If the hissing remains uncontrolled, there is a need to take the cat to the vet on an urgent basis.

Cats Hissing Towards Humans

When the cat hisses at people, it can be out of fear, or it may not be able to recognize.

In such a way, cats sense negative vibes and try to stay away from such strangers to a massive extent.

Furthermore, the cats may be going through something bad and scary, which can change their behavior toward every person around them.

In such a situation, strangers can offer comfort to the cats to make them feel overwhelmed and extraordinary.

How To Overcome Cat Hissing?

Hissing is considered a normal behavior among cats, and it can be solved through a blend of methods and techniques.

1. Keep The Cat Separately

When a cat is hissing, give it some space so that it can relax and calm down.

Try not to bother because it may need some time to absorb the atmosphere and the circumstances in depth.

It would, in the long run, help the cat in soothing effectively.

After getting plenty of time to hide and hiss, cats can feel better about the situation.

With time, when the cat starts recognizing the scents, it can easily adjust and become friendly to mingle.

2. Face-to-face Interaction

Suppose the cats do not show signs of aggression after complete recognition.

Then the perfect time has come for the interaction.

Provide a playful environment to the cat and others so that the habit becomes common.

Offering a slow interaction can also be advantageous in the cats who are more possessive towards supremacy.

Be very attentive to the type of cat’s behavior and hissing style.

3. Develop A Comfortable Relationship Of Cats With Others

The best time to start getting comfortable with other cats is when they’re still kittens. 

Once the cat becomes comfortable with the new environment, it is best to have quality time with the cat.

If there is any hostile or violent conduct, the cat develops in the context of the interaction again. Keep the cats away for some time.

You can swap the towels or blankets they are using so they are able to familiarize each other’s smell or switch their rooms once in a while.

That can help the cats to revert their mood peacefully towards the circumstances.


The hissing is typically normal and treatable, but if it persists for a long time, it may become severe.

The hissing problem of cats can be resolved by eliminating the cause of pain or fear they suffer.

By giving a comfy ambiance, they can come back to everyday life.

They may start eating food, playing with all the toys with full zeal and enthusiasm, and sleeping without stress.

It shows that helping cats makes them happy and cherishes charming and attractive pets to the fullest.

They love you the most, and they are extremely sensitive towards you, so be the source of their happiness.
