How to Introduce Two Cats

Do not start face-to-face

Give the newcomer a separate safe room with food, water, litter, hiding and resting places. Let both cats settle before expecting close contact. A rushed first meeting can make later introductions harder.

Move at the cats’ pace

Start with separate spaces and predictable routines.
Exchange bedding or scents without forcing contact.
Pair calm awareness of the other cat with something positive, such as play or food at a comfortable distance.
Use a barrier or controlled visual access before unrestricted meetings.
Increase shared time only while both cats remain comfortable.

Build a home that reduces competition

Duplicate important resources and spread them around the home. Cats need choices for food, water, litter, scratching, resting, hiding and elevated space.

A practical introduction sequence

A short exercise you can use at home. These are observations and low-risk changes, not a diagnosis or an individual treatment plan.

Start with separate territories

Give the newcomer a quiet room with water, food, litter, hiding spaces and resting areas. The existing cat must retain access to its own resources. Let both settle before any direct meeting.

Exchange information before contact

When relaxed, swap bedding or allow access to each other’s scent on suitable objects without forcing proximity. Use brief, positive experiences on opposite sides of a closed door or safe barrier; stop if either cat is distressed.

Go forward only at their pace

Try short supervised visual sessions with an escape option and abundant space. Staring, blocking doorways, growling, stalking or repeated hiding are reasons to slow down. Forced face-to-face meetings and punishment can make the association worse.

When to get veterinary help

Contact a veterinarian promptly for sudden, severe, persistent or worsening changes. Breathing difficulty, collapse, repeated straining to urinate, seizures or suspected poisoning can be emergencies. Online guidance cannot diagnose your cat.
