cold discharge vs tear duct discharge in rabbits

updated 19 May 2026

if your rabbit has crusty or wet fur around one or both eyes, it is easy to dismiss it as “just a bit of dust.” in Singapore, that instinct can cost you. the heat and humidity here, typically 28 to 32°C and 70 to 90% relative humidity year-round, create conditions where bacterial infections spread fast and discharge dries onto fur within hours, masking how serious the problem has become. HDB flats add another wrinkle: poor cross-ventilation, AC drafts, and close proximity to other pets can stress a rabbit’s immune system even without you realising it. two causes account for most eye discharge in rabbits, and they look similar but need very different treatment. knowing which one you are dealing with changes what happens next.

what cold discharge looks like

“cold” in rabbit circles refers to a respiratory infection, most often caused by Pasteurella multocida, though other bacteria such as Bordetella are also involved. this is sometimes called snuffles.

the discharge from a respiratory infection usually affects both eyes. it starts watery, then turns white, yellow, or greenish as the infection progresses. you will often see nasal discharge at the same time, either clear or cloudy. sneezing is common, sometimes in frequent small bursts.

the rabbit may paw at its face or rub its nose and eyes against the enclosure. in more advanced cases the fur around the nose and inner corners of the eyes mats together. the rabbit may also become quieter than usual and eat less.

respiratory infections in rabbits are chronic in nature. they can go into remission, then flare when the rabbit is stressed or its immune system is compromised. a rabbit that had snuffles as a baby can relapse as an adult.

what tear duct discharge looks like

the tear duct, called the nasolacrimal duct, runs from the inner corner of each eye down toward the nose. in rabbits this duct is narrow and curved, making it prone to blockage.

when the duct is blocked, tears cannot drain properly. they spill out of the eye and run down the fur instead. this discharge is usually clear to slightly milky and affects one eye more than the other, sometimes only one eye at all.

there is no sneezing. no nasal discharge. the rabbit eats normally and acts otherwise well. the fur below the inner eye corner is wet and may stain to an orange-brown colour over time from the porphyrin pigments in rabbit tears.

the most common cause of duct blockage in rabbits is dental disease. rabbit tooth roots sit very close to the duct, and as teeth shift or develop root elongation, they compress the duct from below. this is why vets often take dental X-rays when investigating a single-eye discharge.

how to tell them apart at home

you cannot diagnose the cause yourself, but you can gather useful information before the vet visit.

look at which eyes are affected. both eyes involved suggests respiratory infection. one eye only points more toward a blocked duct, though early respiratory infections can appear one-sided before spreading.

check for nasal discharge. wet nostrils or crusty nostrils strongly suggest respiratory involvement. clean, dry nostrils with one wet eye lean toward a duct issue.

listen for sneezing. occasional sneezing is normal. frequent sneezing, especially in clusters, is a respiratory flag.

check appetite and energy. a rabbit with a respiratory infection often becomes lethargic and eats less hay. a rabbit with a blocked tear duct usually acts completely normal.

look at the discharge texture. sticky, thick, or coloured discharge is more likely bacterial. clear, thin, watery discharge that just keeps appearing suggests poor drainage.

none of these observations replace a vet examination. they just help you describe the situation clearly when you call the clinic.

why Singapore’s climate matters

Singapore’s heat and humidity affect both conditions in ways that matter to rabbit owners here.

bacterial infections that cause respiratory disease thrive in warm, humid environments. if your rabbit is already carrying Pasteurella, stress from heat, a change in routine, or an AC unit blowing directly on the enclosure can trigger a flare.

discharge also dries and crusts faster than you might expect. what looks like a small crust in the morning can represent hours of continuous flow. do not judge severity by the size of the crust alone.

indoor rabbits in HDB flats often experience temperature swings between the cooled interior and the uncooled corridor or balcony. if your rabbit spends time in both areas, that contrast, sometimes 8 to 10 degrees, is a stress trigger.

high humidity also means that matted wet fur around the eyes stays damp. damp fur near mucous membranes is a site for secondary skin infection. check and gently clean the area daily, using plain saline or a damp cloth, not human eye drops or baby wipes.

what the vet will check

a SG exotic vet will typically begin with a physical exam, looking at both eyes and the nasal passages. for suspected duct blockage, the vet may apply fluorescein dye to the eye surface and check whether it appears at the nostril, confirming whether the duct is open or blocked.

for respiratory infections, the vet may take a swab for bacterial culture and sensitivity testing. this tells them which antibiotic will actually work against the specific bacteria present, which matters because Pasteurella strains vary in their resistance patterns.

dental X-rays are often needed if duct blockage is suspected, because the problem is frequently below the surface. standard visible examination of the teeth does not reveal root elongation.

as of 2026, costs in Singapore for an exotic vet consultation typically range from SGD 60 to 150. a full workup including culture, X-rays, and sedation for duct flushing can run SGD 300 to 600 or more, depending on the clinic and findings. this is worth factoring into your planning before the visit.

treatment approaches

respiratory infections are treated with antibiotics prescribed by the vet. the type, dose, and duration depend on the bacteria found. some rabbits need long-term low-dose treatment if the infection keeps recurring. supportive care at home includes keeping the environment stable, ensuring hay intake stays high, and gently cleaning discharge from the fur.

blocked tear ducts are often treated by flushing the duct under sedation to clear the blockage. if dental disease is the underlying cause, the dental problem needs to be addressed too, otherwise the duct will block again. in some cases the duct cannot be fully reopened and ongoing management is needed.

do not put human eye drops, antibiotic drops meant for cats or dogs, or herbal rinses into a rabbit’s eye without vet guidance. rabbit eyes are sensitive and some preparations intended for other species are harmful.

what owners often get wrong

waiting for it to clear on its own. in Singapore’s climate, eye discharge rarely resolves without intervention. bacterial infections spread and dental problems do not fix themselves. a discharge that has been present for more than 24 to 48 hours needs a vet visit, not a watch-and-see approach.

assuming one eye means it is less serious. single-eye discharge from a blocked duct can progress to a periorbital abscess if the blockage is not cleared. abscesses around the eye are painful, difficult to treat, and expensive to manage. catching the duct blockage early is far better.

using general practice vets for diagnosis. most cat and dog clinics in Singapore do not have the equipment or training for rabbit dental X-rays or duct flushing. bring your rabbit to a vet with documented exotic animal or rabbit experience. asking specifically whether the clinic treats rabbits as a regular part of their caseload is a reasonable question before booking.

wiping discharge with scented wipes or human products. many baby wipes and general antiseptic wipes contain ingredients that irritate rabbit mucous membranes. plain saline on a soft cloth is the safe choice for cleaning discharge between vet visits.
