Introducing a new kitten to other pets requires a gradual and controlled approach. Start by keeping the kitten in a separate room, allowing the pets to get used to each other's scents through closed doors. After a few days, conduct brief, supervised meetings, keeping interactions positive and calm. Use barriers like baby gates if necessary. Provide plenty of attention and reassurance to resident pets to prevent jealousy. Gradually increase the time they spend together, always monitoring for signs of aggression or stress. Patience and positive reinforcement are crucial for a smooth transition.
