The rabbits were there first, and the ground floor is their territory. A kitten arriving into that space is, from a rabbit's point of view, a small predator with unpredictable movements, and even a playful chase with no harm intended can injure a rabbit or frighten it badly. A peaceful household is possible, and many cats and rabbits live calmly together, but it is built in stages with barriers and supervision, never on trust alone.
Start Behind a Sturdy Barrier
Begin with scent and sight at a distance. Let the kitten settle in a separate room first, swap bedding between the animals so each learns the other's smell, and keep the rabbits' free-roaming routine unchanged so their world does not shrink because a kitten arrived. Their living space stays separate from the kitten's throughout the introduction, and it remains a refuge the kitten cannot enter.
Then hold staged barrier meetings: the kitten on one side of a sturdy pen, gate, or carrier door, the rabbits on the other side and always free to leave. Short, calm sessions are the goal. Rabbits who approach, graze nearby, or ignore the kitten are showing comfort; a rabbit who thumps, charges the barrier, or hides and stays hidden is asking for more distance and more days at this stage.
Supervised Contact, With an Exit for the Rabbits
Only when both sides stay relaxed through the barrier should they share a room, and then only under supervision, in one room, for a short session. The rabbits must be free to leave at any moment, with clear routes back to their own space that the kitten cannot block. Manage the kitten actively: play with the kitten away from the rabbits, reward calm glances and turned-away attention, and end the session while everyone is still relaxed.
Remove the kitten at the first chase, and the same applies to a pounce, a swat, or a hard fixed stare that does not break when you call or distract. Removing the kitten is not a punishment; it is the rule that protects the rabbits and teaches the kitten that rabbits are not play equipment. Go back a stage after any incident and rebuild slowly, because one frightening chase can undo weeks of careful work and can leave a rabbit afraid in its own home.
The Rules That Stay in Place
Separate living spaces remain even after introductions go well. The kitten sleeps and spends unsupervised time in its own area, the rabbits keep theirs, and shared time happens when a person is present and paying attention. As the kitten grows, its size and play style change, so calm kitten behavior is not a lifetime guarantee; an adult cat with a settled, proven history around the rabbits earns more freedom gradually, and some pairs are simply always supervised, which is a perfectly good outcome.
Watch the rabbits for the quieter signs that shared time costs them too much: eating less hay, hiding more, or avoiding rooms they used to enjoy. Also watch how sessions end. A kitten who can be called away from watching the rabbits, and who settles to play or sleep in their presence, is learning the household's real lesson, that rabbits are background rather than entertainment. A kitten who winds up tighter with every session, stalking from furniture and ignoring distraction, needs the stages stretched over a longer period, with barrier work continuing until that intensity fades with maturity. Their comfort is the measure of success here, not the kitten's enthusiasm. If those signs appear, increase separation and slow everything down.
