Slow introduction techniques for cats involve gradually familiarizing them with each other’s scent, space, and presence to reduce stress and prevent aggression. Start by keeping them in separate rooms, swapping their bedding to exchange scents, and feeding them on opposite sides of a closed door. Gradually allow visual contact through a baby gate or cracked door, followed by short, supervised meetings. These slow steps help build positive associations and trust, making the transition smoother for both cats.
