Prepare a separate space for the kitten with food, water, litter box, and toys. Allow them to smell each other through a closed door to get used to each other's scent.
After a few days, swap bedding or toys between the cat and kitten to further familiarize them with each other's scent. Supervise their first face-to-face interaction in a neutral space.
Monitor their interactions closely. Look for positive body language such as relaxed postures and playful behavior. Reward good behavior with treats and praise to create positive associations.
Give each pet their own space and attention to prevent jealousy. Gradually increase their time together under supervision until they are comfortable with each other's presence.
Be patient as the introduction process may take time. Avoid forcing interactions and allow the cat and kitten to set their own pace. Seek advice from a veterinarian or animal behaviorist if needed.
With time and patience, your cat and new kitten can become friends. Provide plenty of love, attention, and resources for both pets to ensure a harmonious and happy household.
