How to Introduce a Kitten to an Adult Cat — Quick Guide

1. Separate at First

• Keep the kitten in a separate room for the first 1–3 days.
• Both cats hear each other but don’t meet yet.

2. Swap Scents

• Exchange blankets or toys.
• Gently pet one cat, then the other.
• Calm reaction = ready for next step.

3. First Visual Contact

• Use a gate, cracked door, or carrier.
• They can see, but not touch.
• Light hissing is normal.

4. Play Near Each Other

• Play with them on opposite sides of a barrier.
• Positive emotions reduce tension.

5. Short, Supervised Meetings

• 5–10 minutes together in one room.
• Stay close and observe.
• If tension grows — gently separate and try later.

6. Routine Together

• Eat in the same room (with distance).
• Playtime together.
• Each cat should have their own litter box.

7. Full Integration

• Usually 5–14 days.
• Success signs: calm behavior, no hissing, shared play.
