Bringing home a second cat does not guarantee that the two will become friends: some cats prefer not to share their home with another cat. Before introductions, consider whether the change will suit the cat already at home and whether there is enough room for each cat to eat, rest, hide and use a litter tray calmly.
A gradual introduction lets cats first get used to each other’s scent and presence while keeping a safe distance. There is no universal schedule: look for relaxed behaviour from both cats rather than counting days.
Prepare separate areas and resources
At first, keep the new cat in a quiet separate room with their own bowls, tray, resting place and hiding spot. Keep the resident cat’s routines and attention. Before arranging any meeting, make sure both cats can retreat without being trapped near one another.
Separate resting and feeding spots reduce the need to compete for space. Check that gaps or barriers will not let one cat suddenly rush into the other’s room.
- Prepare a quiet separate space for the new cat.
- Keep bowls, trays, beds and hiding places separate.
- Maintain the resident cat’s familiar routine.
Start with scent, then a safe view
When both cats are calmly using their own rooms, offer a cloth or object carrying the other cat’s scent. Place it at a distance and leave the choice open: a cat may approach, ignore it or move away. They can take turns exploring each other’s rooms without an unexpected face-to-face meeting.
If the scent no longer causes noticeable tension, arrange a short look through a secure barrier such as a mesh door. Do not carry a cat to the barrier or hold them facing the other cat. End the session before attention turns into prolonged staring, hissing or attempts to lunge.
Try brief meetings only when both cats are ready
Move to a direct introduction after several calm sessions through a barrier. Choose a place where both cats can move away or get up high, and keep their escape routes open. A brief shared game or treat at a comfortable distance may make the moment pleasant, but do not use food to lure a cat close to the other.
If either cat hides, freezes or starts chasing the other, calmly end the contact and return to an easier stage. If conflict repeats or you cannot safely separate the spaces, discuss a plan with your vet or a qualified behaviour professional.
SMALL STEPS OF CARE
What you can do
- Give each cat a safe separate space and their own resources.
- Keep the resident cat’s usual routine.
- Move from scent to a barrier only when both cats are calm.
- Leave an exit and room to move apart at every stage.
- Pause at signs of tension and return to an earlier step.
What to avoid
- Putting the cats in one room immediately or holding them close together.
- Continuing when a cat is hiding or trying to leave.
- Assuming that no fight means the cats are friends or ready to live together.
