Introducing a new housemate to your adult cat

Bringing a new kitten into a house where an adult cat already lives can be a tricky process. Cats are known for their territorial nature and introducing a new feline can cause stress and anxiety for both parties. But with proper planning and patience, the process can be smooth and successful. In this step-by-step guide, we discuss the best ways to introduce a kitten to an adult cat at home. From creating a safe and comfortable space for the kitten to gradually introducing the two cats, we cover everything you need to know to ensure harmonious co-existence between your cats. So, whether you are a seasoned cat owner or a first-time kitten parent, this information on how to introduce a kitten will definitely lend a hand.

Understanding your cat's behaviour

Before introducing a kitten to an adult cat, it is important to understand your cat's behaviour. Since cats are territorial animals by nature, they may react aggressively to newcomers in their living space. It is important to understand that introducing a kitten is a big change for the adult cat and may take time to get used to.

An adult cat may give off different signals to indicate that it feels threatened. These can range from barking and growling to shaking out its fur or showing its teeth. It is important to recognise these signals and understand that the adult cat needs time to accept the new family member.

The personality of the adult cat is also important. Some cats are naturally social and are fine with accepting new cats, while others are more self-centred and thus need more time.

Preparing your home for a new kitten

Before introducing a kitten, the house will need to be safe for both cats. Make sure your home has enough space for both to play, run around and also have their own space.
>br/> Place litter trays, food and water bowls in different places in the house to ensure that both cats can always access their food, drink and toilet. Also make sure that your home is free of poisonous plants and that the cats do not have access to dangerous areas, such as a fireplace or a balcony without a railing.

Cat furniture, such as scratching posts, will also help your cats feel safe and comfortable in their new environment. Purchase enough cat toys and scratching posts for your cat to have fun with. Also to reduce any stress.

Introducing your kitten to a safe space

The first step in introducing a kitten to an adult cat is to keep the kitten in a confined space. This can be a separate room or a special cat cage. This gives the adult cat a chance to get used to the kitten's smell and sound without making direct contact.

Make sure the kitten's safe space has adequate facilities: a litter tray, food and water bowl and a nice bed for it to sleep in and where it feels safe. It is also important that the adult cat cannot enter the kitten's safe space.

Allowing controlled interactions between kitten and adult cat

Once the kitten feels comfortable in the safe room, introductions can slowly begin. Place both animals in the same room, but under supervision.

Keep initial introductions short and pay close attention to the behaviour of both cats. If either cat shows signs of stress or aggression, take the kitten back to the safe room and try again at a later time.

Should they feel uncomfortable, it is important that both cats can escape to a space of their own. This space should have a litter tray and a water and food bowl. So that everything important to them is also accessible.

Introducing scents

As you gradually increase the encounters between the kitten and the adult cat, you can start introducing scents of the other cat. For example, by placing the cats alternately in the safe room, so they can get used to each other's scent.

Feeding and playing together

Once the cats are comfortable with each other, it is fun to feed and play with them together. Give both cats enough space so they don't have to enter each other's territory. Remember to reward your cats for good behaviour; this will reduce their stress levels.

How to avoid conflicts between the two cats

Although most introductions go smoothly, conflict can still arise between the kitten and the adult cat. Therefore, stay with them in the beginning to ensure both's safety.

If one of the cats becomes aggressive, take the kitten back to the safe room and try again later. Do not punish your cat for aggressive behaviour, this can cause a lot of stress and it will worsen the situation rather than improve it.


Introducing a kitten to an adult cat can be a challenging process, but with the right planning and patience, it can be fine. Give your cats time to adjust to the new situation at their own pace and be patient and consistent in your approach, by doing so you can foster a good relationship between your cats. Remember that each cat has its own personality and it is important to understand what your cat needs to feel comfortable. We hope that with this step-by-step article, you can help your cats have a great time together.
