How to Introduce Your Kitten to Your Multi-Cat Home (Step-by-Step Guide)
Welcoming a new kitten into your home is a joyful and exciting event. However, if you have other cats who have reigned supreme in your home for several years, this new furry mini companion may be the most upsetting thing for them. So, how do you make sure that the adaptation is made in the smoothest way possible? Don’t worry. In this article, you will find all the do’s and don’ts to make it easier for your adult cats to adjust to your cute and fluffy new kitten.
Before The New Kitten Arrives
If you want to have two or more cats in your household, your best bet is to adopt them at the same time or adopt the second one as soon as possible. Acceptance will be better if there is not a big difference in age between the two cats. Indeed, an old cat will have a hard time putting up with the playfulness of a kitten. Playing, miming fight scenes are part of a kitten’s normal behavior, and the kitten will seek out its companion. So, the younger your first cat, the easier it will be to adapt to the novelty. It is estimated that before the age of four, a cat more readily accepts the arrival of a new kitten.
Rivalry Between Males
In general, cats of opposite sexes accept each other better, and cohabitation between females is generally quite good. Besides, sterilization tends to decrease conflicts. On the other hand, the rivalry between two males is always important. The males, even castrated, are indeed very territorial. One essential thing to consider is the personality of your two cats. The character of the new cat should “stick” as much as possible to that of the oldest.
Step 1: Planning The Arrival of The New Kitten
The introduction of the new kitten should be carefully planned. First, you must consider that adopting a new kitten could put your existing pets’ health at risk if not done properly. Before bringing the kitten to your home, you should make sure it is not suffering from any infectious diseases that could be transmitted to your other pets. Get the kitten checked by a vet and check that your other cats’ vaccination schedules are up to date. The kitten should be quarantined, rechecked, and cleared by a vet before you introduce it to your cats. Make sure that Feline Leukemia Virus and Feline Immunodeficiency Virus tests have been performed and that vaccinations and pest control treatments are up to date. This will reduce any potential health risks.
Most cats are not ready to accept a new family member; they need time to get used to the idea. Therefore, it is essential to have patience and not to rush things. That said, take note of our tips to introduce a new kitten to your multi-cat home!
Step 2: Isolate The Newcomer
Upon arrival, the new kitten should be isolated in a room, such as a bedroom, so that there is no possible eye contact with your other cats. Open his transport crate and let him explore his room in peace. Take this transport crate and leave it in the living room, within reach of the other cats in the house, so that they can explore and smell it. Watch their behavior: they may growl and hiss around the kitten’s carrier or simply approach it curiously and sniff it enthusiastically. Leave the crate with your other cats until they no longer show interest. About an hour after you have locked the kitten in the room, you can go back there. Cats need to explore their surroundings before they can interact socially. Sit calmly and let him approach you without forcing contact. Come see him three or four times a day in his room.
Step 3: Reassure Your Other Cats
The cats in the house may start to growl when you come back to them because you smell the “odd one out”. They will probably stand in front of the room where the kitten is and start sniffing the door. Do not proceed to the next step until the hostile reactions to the scent of the new kitten, door, and carrier cease. It is important to behave with your other cats in the usual way, giving them time and reassuring them. When you feel that your cats have become used to the newcomer’s existence, it’s time to move on to the next step, which is getting them to see each other but without physical contact.

Step 4: Prepare The First Face-To-Face
Finally, proceed to the fourth step when the cats seem relatively calm in the presence of the other, and the hissing and growling are minimal. Then, you can open the bedroom door, staying out of the way. If your cats start to fight, clap or yell in a way that scares them, but without trying to intervene by hugging a cat. The whole process can take from days to weeks or even longer. Do not be discouraged and be patient.
Step 5: Identify Signs Of Anxiety
You will need to watch for signs of stress in your cats. For example, excessive grooming, vomiting after eating, or loss of appetite are signs of anxiety. It is important to provide separate bedding and eating areas to limit stress. Over time, they may declare a truce and even come closer (groom each other or even share rest areas).

What You Must Not Do
Punish Your Cats
If your cats are arguing, don’t intervene by punishing them. Instead, you should take a few steps back and calmly separate them for a short period. Then, reintroduce them and take the opportunity to reinforce calm behavior by giving them treats while they are together. Make sure you feed each cat directly in the mouth or in a way that does not cause competition between them. Indeed, contrary to popular belief, punishing cats for arguing might actually encourage them to continue the conflict. Instead, use the magic of reinforcement to change their emotions and help them perceive each other as something more positive. Do not leave the cats together unsupervised for extended periods until you are sure they can get along peacefully. This can be achieved by gradually and patiently increasing the time they spend together while continuing to offer a treat for calm behavior.
Intervene Too Frequently
It is essential to let your cats go at their own pace. The sooner the negotiations are completed, the sooner calm will return. Excessive interference from you could delay the process. Make sure you keep an eye on their behavior and prevent heavy fights, injuries, or if one of the cats shows persistent signs of anxiety. If this happens, isolate your cats and contact your veterinarian or feline behaviorist for help.
