The ASPCA estimates that each year, over 3.4 million cats enter shelters across the country. Of those that are not later returned to their owners, 37% are adopted. It’s more than likely that some of those kitties will make their way into homes which already house a cat. But how to easily introduce two cats?
The world has millions of cats that need loving homes, and many people who already have a cat often choose to get another one – whether that’s through adoption programs, breeders, or just taking on a neighborhood stray. It’s a kind option, provided you have the time, resources, and space to look after more than one cat.

Getting Another Cat
Cats are like chips, you can’t have just one! So in due time, your one cat might turn into two. Now you’re wondering, but how can I introduce them without there being a cat fight?
First and foremost, getting another cat is no light decision. As you all know, you should adopt and not shop when considering adding more felines to your home.
The ASPCA has a list of shelters and registered places to adopt from. You can be sure that you are giving a needy animal a home, or an unloved one a second chance, saving it from potential euthanasia.
So now you have your precious second (or third, or fourth..) kitty in your new home. How do you introduce your new cat to other felines?
How to Introduce Two Cats: Some Practical Concerns
We’ll start here with some of the more superficial, physical necessities to owning more than one cat.
More Litter Boxes
Two cats, obviously, exponentially increases the amount of cat-related items you might need.
Cats, being more independent by nature, don’t tend to share (at first).
So some items – such as food bowls and cat beds will be needed in duplicate. Some items will even need to be tripled (read our article on cat litter boxes). This is a hygiene concern as much as anything else but may also take a toll on your finances, so plan accordingly.
Special Diets (Kitten, Adult, Senior)
Does your new cat eat the same food as your first one?
Or will it require a more sensitive diet? If it has a thyroid issue or perhaps is just a different age. These are the things to consider, as you will need to institute a strict feeding policy (i.e – not letting one greedy cat gobble everything up, or eat prescription food).
Do you have enough space to accommodate another cat? For the initial meetings – do you have separate places that they can retreat to?
Cats are notoriously territorial. If you’re wondering how long it takes two cats to get used to each other, it can take longer than you think. Our Yoda always takes around 2 weeks to get comfortable with another cat.
Cats should be spayed or neutered before leaving the shelter and coming to your home. But all of this comes secondary to the question that cat owners must ask themselves before they proceed any further: how will the two cats react to one another?
Step-by-Step Guide: How to Introduce Two Cats
You may be wondering: how long does it take cats to get used to each other?
When wondering how to introduce two cats, the common wisdom is to do “one sense at a time”.
Rather than placing both in the same room and expecting them to accept the new situation, you must handle them delicately.
The time scale can be a lengthy one, taking several days or even weeks depending on their personalities.
As you already know, cats are sensitive to changes, and while they can’t tell you they are stressed, they will express it in their body language. A very stressed cat may end up with a UTI due to increased constipation, which can in some cases be fatal.
First Step: Introducing Their Smell
The day you bring the second cat home, make sure any contact with your first cat is prohibited. Isolate them in separate areas.
Next, you should ‘swap scents’. This means you take a towel and rub it on a scent gland (the cheek contains the most) of one cat, and present it to the other. This can also be achieved by presenting some of one cat’s bedding to the other. However you choose to do this, do it both ways so each cat has a chance to get used to the other’s smell.
Second Step: Letting Them See Each Other
The cats must be able to see one another. If you have a transparent screen door, you need to get the cats on either side of the glass. If not, leaving a living room door ajar, and letting the cats see another through the opening will also suffice. This is a territorial concern. As cat behaviorists have noted,
“From the resident cat’s perspective, there’s an intruder in his territory. From the newcomer’s point of view, she has just been dropped on hostile turf. Both cats need to feel secure.”
Feeding the cats together (after a requisite amount of time allowed to appreciate each other’s existence) can also be beneficial, provided you supervise the whole time.
Feeding while cats are in sight, or in distance of smelling each other reinforces a positive feeling (eating food) with the presence of another cat. Stressed cats may not eat, so it’s important to get them to make this connection.
Third Step: Positive Reinforcement
Cats learn through positive reinforcement, so praise them when they are calm around each other. Caress and love on both cats equally while in front of the other one. Reward with treats!
What Not to Do When Introducing Two Cats
Never force two+ cats to like each other, as this will probably ruin their chances of forming a connection.
Storytime: Yoda and Peter
How to introduce two cats is not always obvious.
What we as cat parents would think is best, may not be after all.
About two months ago (now 2 years ago!), we moved into a temporary little studio in the Netherlands while the owner of the place went on holiday. While she was away, we offered to take care of her cat, Peter.
Peter is a lazy, gentle, somewhat over-sized, white and black cat with big green eyes. Long story short, we had to introduce Yoda and Peter. We thought this time around we would just to let them “do as they do” and just see what happens. Low growls emitted from both of their stomachs. We knew this wasn’t the best way.
From Strangers to Fur-iends
So we decided to start over.
Yoda was afraid as Peter’s scent was covering the house everywhere, he was basically thrown into a new environment, and he felt vulnerable.
We wanted Yoda to sniff around the place, so we let Peter outside (as he is allowed), so that Yoda could explore his new home.
When Peter and Yoda were in the house at the same time, we would separate them into two parts of the house during the day, and during the night we would have them swap rooms so they could get used to each other’s scent without having to see each other directly.
We also gave them their dinner on either side of a closed door. This way, both Yoda and Peter could have the positive association from food while smelling one another close by.
After a day we would crack the door, and continued like this until the door was wide open, allowing them to eat right next to each other.
Within one week, as they both were allowed to roam freely through the entire studio, I witnessed that they cautiously approached each other. Yoda let out a cute little trill, followed by one brief nose bump, and just like that two strangers became friends.
Final Thoughts: How to Introduce Two Cats
In conclusion, introducing two cats requires patience. Simply, introduce them slowly. Increase exposure over several days or weeks. In other words, don’t rush it.
It can be easy to get disheartened during this period. However, stress not. It might take a few days, but in the end, your cats can become the best of fur-iends.
