方法 to Introduce a New Cat to あなたの Household

Bringing a new cat into a home with existing cats requires patience and structure. Cats are territorial, and a rushed introduction can lead to aggression and long-term relationship problems. A gradual introduction over one to three weeks gives both cats time to adjust.

Prepare a Separate Room

Set up a dedicated room with litter box, food, water, scratching post, and resting spots. This becomes the new cat's territory for the first week or more. The closed door allows both cats to detect each other's scent without face-to-face stress. The new cat can decompress from the move while your resident cat adjusts to an unfamiliar presence.

Scent and Site Swapping

After a day or two, exchange scents between cats. Rub a cloth on the new cat's cheeks and place it near your resident cat's food bowl. Do the same in reverse. Swap bedding between rooms. Then let the new cat explore main living areas while your resident cat visits the new cat's room. This gives both cats a chance to investigate scents throughout the home without direct encounter.

Visual Introduction

Crack the door or use a baby gate for visual contact. Feed both cats on opposite sides of this barrier. The goal is to associate seeing the other cat with something positive. Start with bowls far apart and gradually move them closer over several sessions. If either cat shows aggression, increase distance and slow down.

Supervised Meetings

When both cats eat calmly within sight of each other, allow short supervised meetings in a neutral area. Keep first sessions to five or ten minutes. Have treats ready for calm behavior. Do not force interaction. Hissing and posturing are normal initially. Separate cats if aggression escalates beyond hissing to swatting or chasing.

Signs of Progress and When to Seek Help

Successful integration looks like curiosity without aggression, eating in the same room, and eventually resting in the same area. Some cats become companions. Others simply coexist peacefully. Both are acceptable. If aggression persists after three to four weeks, consult a veterinary behaviorist. Pheromone diffusers and sometimes medication can help reduce stress. A patient, structured introduction protects both cats from unnecessary stress.
