✓ Successful introductions begin with separation and scent.
✓ Progress through closed-door feeding, scent exchange and secure visual contact.
✓ Go back a stage when either cat cannot relax or eat.
Successful introductions begin with separation and scent. This guide turns the idea into small practical steps while keeping health, choice and individual temperament in view.
Start here
Successful introductions begin with separation and scent.
A practical plan
Progress through closed-door feeding, scent exchange and secure visual contact.
Know when to pause
Go back a stage when either cat cannot relax or eat.
Build safety before visual contact
Give the newcomer a complete base room with food, water, litter, scratching, hiding and height. Keep the resident cat's routine stable. Exchange bedding or scent cloths only while both cats remain comfortable, and feed on opposite sides of a closed door at a distance where each cat can still eat normally.
Advance according to behaviour
Use a secure barrier for brief visual sessions and provide escape routes on both sides. Relaxed eating, play, grooming and the ability to look away support gradual progress. Persistent staring, blocking, growling, hiding or food refusal means increase distance or return to the previous stage. After fighting or injury, separate safely and seek veterinary or qualified behaviour guidance.

Common mistakes
×Waiting for a dramatic symptom instead of noticing smaller changes from the cat’s normal routine.
×Changing several things at once, making it difficult to learn what actually helped.
×Treating general guidance as a substitute for advice from a veterinarian who knows the individual cat.

A third cat will not automatically entertain the others or solve loneliness. Decide based on space, existing relationships, resources, finances and your ability to introduce slowly.
