How to Introduce a New Kitten to a Resident Cat

Go slow — keep the kitten in a separate room for the first week, swap scents, then allow short supervised meetings. Rushing is the #1 cause of a failed introduction.

The timeline that works

• Days 1–3: kitten in its own room; feed both cats on opposite sides of the door.
• Days 4–7: swap bedding and rub each cat's cheeks with a cloth, then place it near the other.
• Week 2: short, supervised face-to-face sessions; end on a positive note with treats.

Set both cats up to succeed

• Give each cat its own litter box, food, water, and scratching posts.
• Use vertical space (cat trees, shelves) so the resident cat can retreat.
• Never force contact; let the resident cat set the pace.

FAQ

Q: Should I let them hiss at each other?

Q: Is it better to get two kittens instead of one?
