You fell for a new kitty and your heart already melts for that tiny nose? Now comes the delicate part: introducing them to your resident cat without drama or jealousy. With a pinch of planning and a lot of softness, this meeting can turn into a lovely story.
What to prepare before your new cat arrives
The secret to a calm welcome? Two clearly defined territories at the start. Set up a dedicated room for the newcomer with water and food bowls, litter box, scratching post, a cozy hideout, and a perch.
Golden rule for cleanliness and peace: one litter per cat plus one extra, placed in separate, quiet areas. Don’t swap boxes early on — each cat keeps their own private spa.
Have high-value treats ready, a soft blanket, and if possible, a calming pheromone diffuser. A quick vet check before introductions helps, especially if one cat has a sensitive health history. Wondering how to spot subtle anxiety? See the early signs of stress in cats.
Scent-first discovery of the new territory
On arrival, place your resident cat in another room. Let the new cat explore their safe room alone — no visual or direct sniffing yet. Give them time: hiding, listening, and slowly expanding their map is normal.
Reward tiny acts of bravery (peeking from under the bed, climbing the perch) with a treat. The more the room smells like “them,” the faster they relax.
Pro tip: slip soft cloth coasters under each food bowl (one per cat), then swap them after 24 hours. You’re pairing the other’s scent with mealtime comfort — surprisingly effective and very low-stress.
Common mistake to avoid: letting them “accidentally” cross in the hallway. An unplanned face-to-face can create a bad first impression and slow the whole process.
Fun fact: for cats, scent beats sight. They read rooms — and other cats — via olfactory markers before any real-world meeting.
First meetings… through the door
Move to controlled visuals. Place their meals on each side of the closed door. Start at a comfortable distance, then gradually move bowls closer over days — only if both eat calmly.
If one hesitates or hisses, increase distance and scatter a few treats to redirect attention. Patience plus positive reinforcement always wins.

Gradual closeness and shared moments
Once both cats eat relaxed near the door, offer short parallel play sessions (wand toy on each side). The goal is simple: the other cat = fun things happen.
Trade scents more precisely: swap toys and blankets, or gently rub both with the same soft glove. Reward during and right after each step so good feelings stick.
Multiply resource zones in duplicate: water stations, beds, scratching posts. For smooth litter habits from day one, check this guide to choosing the right litter.
Behavior bonus: cats who accept eating just a few inches apart already show a high level of social tolerance — that’s a very positive sign.
Open the door: the real-life meet
When everyone looks loose and happy, open the door for a short session. Let them observe, sniff, then end on a positive note (treats, a quick game). Better several tiny wins than one long, tense meeting.
Never do this: “let them sort it out.” Feline conflicts can leave long-lasting traces. If tension rises, calmly interrupt with a cushion or a sheet between them — never your hands — and try again later.
Notice the calming signals, too. A little kneading or cheek rubbing already sends good vibes. Curious? Here’s what kneading really means.
Need an extra nudge?
If after several days tension lingers, step back one phase and lengthen the scent-desensitization period. Predictable routines help: same hours, same rituals.
Original trick: install two stacked baby gates in the doorway and clip a towel over them, covering 80%. Uncover a few more inches each day so visual exposure grows gently while everyone stays safe.

FAQ
How long does it take for a new cat to be accepted?
Anywhere from a few days to several weeks, depending on temperament and past experiences. Go step by step and celebrate small wins.
Should I intervene if my cats argue?
Yes — but not with your hands. Interpose a cushion or sheet, redirect with treats or play, then return to the previous phase.
Should cats share a litter box at first?
No. Provide one box per cat plus one extra, in separate, quiet spots. It prevents territorial stress and accidents.
What are the signs that intros are going well?
They eat or play in each other’s presence, groom calmly, rest in the same room, and move around without hard staring or blocking.
