How to introduce two cats slowly
A good cat introduction begins with complete separation, then scent, closed-door routines and brief visual contact. Progress depends on relaxed behaviour, not a deadline.

✓ Begin with separate spaces and resources
✓ Exchange scent before face-to-face meetings
✓ Move back a step if either cat remains distressed
Successful introductions are usually gradual. The goal is not instant friendship, but repeated experiences in which both cats feel safe.
Introduce cats without rushing the distance
Progress means both cats can remain comfortable, not that they must meet quickly.
- 1Begin separately
Give the newcomer a complete safe room with food, water, litter, rest and hiding choices.
- 2Exchange familiar scent
Swap bedding or scent cloths and pair the other cat's scent with calm routines and food.
- 3Use a secure barrier
Begin brief visual contact through a barrier and increase time only while both cats cope well.
Start separately
Give the newcomer a quiet room with food, water, litter, hiding places and comfortable resting areas.
Build familiarity
Swap bedding or use a soft cloth to transfer scent. Feed on opposite sides of a closed door at a distance each cat accepts.
Keep meetings short
Use a secure barrier for early visual contact. End while both cats are still coping, and avoid forcing them close together.
Prepare two complete territories
The newcomer needs a secure room with food, water, litter, hiding, scratching and height. The resident cat keeps access to familiar resources. In the wider home, provide multiple separated feeding, water, sleeping and litter locations so neither cat must pass the other to meet a basic need.
Move forward only when both cats can cope
Begin with scent exchange and positive routines on opposite sides of a closed door. Later use a secure visual barrier at a distance. A hiss is information, not failure, but fixed staring, stalking, lunging, food refusal or inability to settle means increase distance and return to an easier stage.

Hiding is a normal safety and rest behaviour, but new or prolonged hiding can be an early sign of pain, fear or illness. Compare appetite, litter use, movement and social contact with the cat’s baseline.
