Before you bring the new cat home
Set up a quiet “base room” for the new cat with litter, food, water, hiding spots, and a scratching post. The resident cat should keep their usual territory at first.
Trim nails if needed, and make sure both cats are healthy (fleas, vaccinations, and a vet check for the new arrival when possible).
Step-by-step introduction
- Day 1–3: Keep cats fully separate. Swap bedding or wipe each cat with a clean cloth and leave the scent in the other space.
- Feed both cats on opposite sides of a closed door so mealtimes feel positive near each other.
- Next: brief visual contact through a cracked door, baby gate, or carrier — a few minutes, then stop while things are still calm.
- Short supervised sessions in a shared room. End on a good note; do not wait for a fight.
- Gradually increase time together over days or weeks. Some pairs take a month or more — that is normal.
Signs to slow down
Flattened ears, prolonged staring, chasing that does not stop, blocked litter use, or hiding for long periods means go back a step.
Never punish hissing — it is communication. Give space and try again later with more scent work.
When to get help
If introductions stall for weeks or either cat stops eating, speak with your vet or a qualified cat behaviour professional. MateLoop also lists cat care services near you.
