Introducing cats.
Build familiarity in small steps, at the cats’ pace.
Calm is the cue to move forward. If tension builds, return to an earlier step.
STEP 01
Start with separate spaces
Give the newcomer a quiet room with their own essentials and let them settle before introductions. Check health and separation needs with your veterinarian first. Resident cats should also have their own food, water, litter boxes, resting places, and hiding spots so they do not have to compete.
STEP 02
Let scent come before sight
Exchange bedding so each cat can investigate the other’s scent without a face-to-face meeting. When they are relaxed, let them explore each other’s spaces at different times. Pair this growing familiarity with things the cats enjoy, such as treats, food, or play.
STEP 03
Keep meetings gradual
Move from separation to controlled visual introductions, then brief supervised time together only when both cats remain calm. Ask your veterinarian for a setup suited to your cats. Keep sessions short and return them to separate spaces between meetings. There is no fixed timetable for becoming comfortable.
STEP 04
Pause when tension appears
Hissing, swatting, chasing, or an impending fight are reasons to slow down and separate the cats safely. Never let them fight it out. If introductions are not progressing, ask your veterinarian or a qualified behavior professional for help. Sudden behavior changes or a cat stopping eating also need veterinary attention.
