Bringing Home a New Kitten? Here’s How to Introduce Them to Your Cats

Written by Jessica Thompson, DVM

First off, congratulations! Introducing a new kitten to your cat takes patience, planning, and a calm, gradual approach. Even the sweetest cats are naturally territorial, and bringing a new kitten into their space can trigger stress, anxiety, or defensive behavior. With the right steps, you can help both cats feel safe and set the foundation for a positive relationship.

Before your kitten arrives, prepare your home. Make sure you speak with the foster family first about what the kitten likes to play with, foods they have been eating and treats they like. If possible, introduce your resident cat to the kitten’s scent using a blanket or toy. Set up a separate room for the kitten with their own food, water, litter box, bedding, and toys. This gives your kitten a safe pace to adjust and prevents your resident cat from feeling their territory is immediately threatened.

Once the kitten is home, allow both cats to get used to each other’s scent. Swap bedding, toys, or food bowls between them, and let each cat explore the other’s space while they remain separated. This helps them become familiar with one another in a low-stress way.

When both cats seem comfortable, allow their first face-to-face meeting. Mealtime is often the best time for this, as both cats are focused on something positive. Some hissing or growling is normal as they establish boundaries but please intervene if tension escalates.

After the initial meeting, separate them again and gradually increase the time they spend together. Be sure to give both cats equal attention, affection, and treats to prevent “jealousy” and reinforce positive associations. Avoid taking sides or trying to determine a “top cat” they should work this out naturally.

With patience, consistency, and plenty of positive reinforcement, most cats learn to coexist and often form a strong bond over time, making your multi-cat household a happy one.
