introducing a rabbit to a resident cat in SG flats

updated 13 May 2026 by xavier fok

owners with both a cat and a rabbit in SG HDB flats are common enough that asking “will they get along” comes up monthly in owner spaces. the honest answer: some pairs work beautifully, some never tolerate each other, and you have to assess your specific cat before the rabbit arrives.

assess the cat first

before bringing the rabbit home, assess your cat:

low-risk cats:

older than 5
calm temperament generally
low prey drive (doesn’t stalk birds at the window, doesn’t chase shadows obsessively)
already used to small animals in the home
has been around children without prey-style behaviour

medium-risk cats:

young adult (1-4 years)
moderate energy and interest in moving things
chases laser pointers and toy mice but not obsessively
some prey behaviour but generally calm

high-risk cats — abandon the introduction:

intact (unneutered) males or females in heat
strong prey drive — stalks birds, watches insects with focused intensity
has injured small animals in the past
young (under 1 year, full hunt-drive period)
any history of going outdoors and hunting

if your cat is high-risk, do not introduce a rabbit. find the rabbit a different home or do not bring it home in the first place. cats with strong prey drive cannot reliably be trained out of it. one bad day costs the rabbit’s life.

the safety setup

assuming your cat passes assessment, the setup before introduction:

separate spaces.

the rabbit needs a dedicated room or enclosure that the cat cannot access. door closed, baby gate, or wire-top enclosure that the cat physically cannot enter or reach into.

cat-proofed enclosure.

if using a wire-top enclosure rather than a closed room, the top must be solid enough that the cat cannot sit on it (rabbits register cat-above as predator). full-height enclosure with closed top is better than open-top with chicken wire across.

escape proofing.

cats can squeeze through smaller gaps than you’d expect. if your “rabbit room” door has gaps under it, the cat can get in. solid-base doors with seal strips.

food and litter separation.

cat food contains taurine and is bad for rabbits. cat litter contains clay and is bad for rabbits. these stay in the cat’s area only. rabbit hay, food, and water stay in the rabbit’s area only.

the introduction protocol

phase 1: scent only (weeks 1-2)

cat and rabbit cannot see each other. exchange scent via:

a small towel rubbed on the cat, placed in the rabbit’s enclosure (and vice versa)
the rabbit’s room door is the boundary
both pets continue normal life in their own spaces

monitor for stress signals on both sides: rabbit thumping, cat growling at the door, refusal of food. if both pets relax over 1-2 weeks, proceed to phase 2.

phase 2: visual through barrier (weeks 3-4)

introduce visual contact through a baby gate or wire mesh.

supervised sessions only, 5-10 minutes initially
both pets must have escape routes (the rabbit retreats into the enclosure, the cat retreats from the gate)
do NOT pick either animal up during this phase
end each session positive (treat for the cat, hay for the rabbit) before either gets agitated

watch the cat carefully. behaviours to flag:

tail flicking or low growling = abandon today’s session, try shorter tomorrow
crouching, dilated pupils, focused stare = serious prey behaviour, may need to abandon introduction
relaxed posture, slow blinks, walking past without interest = excellent, proceed

watch the rabbit:

thumping = stress, end session
relaxed eating and movement near the gate = comfortable, proceed

phase 3: same-room supervised (months 2-3)

once both pets are comfortable with the barrier, introduce same-room sessions.

always supervised, never alone
rabbit on the floor in a familiar area, cat in another part of the room
you sit between them initially
10-15 minutes maximum
end before either gets stressed

over weeks, the cat learns the rabbit is a normal household feature, not prey. the rabbit learns the cat is large but not actively dangerous.

phase 4: ongoing supervised cohabitation (months 4+)

assuming all goes well, both pets can be in the same general space with you present. they probably will never actively interact. that’s the goal — peaceful indifference.

never leave them unsupervised together permanently. even very good pairs have bad days.

SG flat realities

practical issues for HDB:

many SG flats are 2-3 bedrooms total. dedicating a room to the rabbit reduces your space
cats sometimes find tiny gaps in poorly-sealed HDB doors. supplement with weather-strip or door sweep
aircon ductwork can be a cat-access route in older flats (rare but check)
if you have a balcony, the rabbit should never have unsupervised access since cats follow

emergency response

if the cat ever attacks the rabbit, even minor:

separate immediately, no reintroduction without major reassessment
vet check the rabbit (cat saliva carries bacteria that cause Pasteurella in rabbits, fatal if untreated)
consider whether the cohabitation should continue. one attack often signals a fundamental prey-drive issue

even superficial cat-bite wounds on a rabbit need antibiotics within 24 hours. don’t wait.

what owners often get wrong

three patterns from SG mixed-pet households:

starting the introduction too fast. “the cat seems fine!” after one supervised hour does not mean they’re integrated. months, not days
trusting an unsupervised period. even a couple of minutes in the same room unsupervised is risky. supervise always
not assessing the cat honestly. owners want it to work, so they overlook prey-drive signs. high-risk cat means no rabbit, full stop
