How to introduce two cats slowly
Introduce two cats in stages: complete separation, low-pressure scent exchange, calm closed-door routines, secure visual contact and brief supervised time together. Move forward only while both cats can eat, rest and walk away normally.

✓ 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.
Prepare two complete living areas
Before the newcomer arrives, create a closable base room with its own food, water, litter, hiding, scratching, rest and height. Preserve the resident cat's familiar resources and routine. Check doors, windows and transfer routes so an accidental meeting cannot happen.
Begin with full separation
Let each cat eat, drink, toilet, groom, explore and sleep normally on its own side of a closed door. Do not hold cats near each other or use a carrier for forced viewing. Hiding, food refusal, door patrol or inability to settle means the distance or difficulty should be reduced.
Exchange scent without pressure
Swap bedding or allow separate exploration of each other's rooms only when both cats remain comfortable. Pair the other cat's scent with meals, play or calm attention at a distance. Never rub a scent cloth on a cat or place it in the only bed or hiding place.
Add sight and shared space gradually
After calm closed-door sessions, use a firmly secured barrier that neither cat can climb, squeeze through or knock down. Keep sessions short with escape choices on both sides. Later, use a room with several routes for brief supervised contact and end while both cats are still coping.
Pause when either cat struggles
Fixed staring, stalking, blocking, repeated chasing, spraying, sustained hiding or appetite change means return to the last comfortable stage. After a fight, separate with a barrier rather than hands. Sudden aggression needs veterinary assessment, and persistent conflict deserves qualified feline behaviour help.

Questions cat people ask
How long does an introduction take?+
It can take days, weeks or longer. Progress should be based on relaxed behavior, not a calendar target.
Does hissing mean the introduction has failed?+
No. Hissing communicates discomfort and a need for space. Increase distance and return to an easier step.

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.
