rabbit anaesthesia risk in Singapore, what to know before surgery

updated 13 May 2026 by xavier fok

before any rabbit surgery in SG, the conversation worth having with your vet is about anaesthesia protocol. it makes the biggest difference to outcomes. unfortunately, many owners don’t know what to ask, and some general vets don’t volunteer the details.

why rabbit anaesthesia is harder

rabbits respond to anaesthesia differently from cats and dogs in several ways:

1. they cannot vomit.

a key safety mechanism in cats and dogs (preventing aspiration if regurgitation occurs) doesn’t apply to rabbits. they need a different pre-op protocol.

2. they have small lung capacity relative to body mass.

less reserve if anything goes wrong. faster oxygen desaturation during complications.

3. they have high stress response.

stress hormones during induction can affect drug pharmacokinetics. a stressed rabbit responds differently to the same drug dose.

4. their core temperature drops quickly.

surface area to mass ratio means heat loss during surgery is rapid. without active warming, hypothermia develops quickly.

5. anaesthetic clearance can be unpredictable.

some commonly-used anaesthetic drugs are metabolised slowly or unpredictably in rabbits.

what good anaesthesia looks like

a well-run rabbit anaesthesia includes:

pre-op:

thorough physical exam
pre-operative blood work for rabbits over age 4 or with prior issues
NO fasting (unlike dogs and cats) — give the rabbit food up until 1 hour before
IV catheter placement before induction
pre-medication (often opioid + sedative) tailored to rabbit pharmacology

induction:

gas anaesthesia (isoflurane or sevoflurane) is significantly safer than injectable-only protocols
gradual mask induction
pre-oxygenation before gas is started

during surgery:

continuous monitoring: heart rate, respiratory rate, blood oxygen, temperature
active warming (heating pad, warm IV fluids)
IV fluid administration throughout
pulse oximeter, capnograph
experienced staff focused on monitoring, not just the surgery

recovery:

close monitoring during emergence
temperature maintained
pain management initiated as soon as appropriate
monitored until eating and pooping

the five questions to ask

before booking surgery, ask:

1. how many rabbit surgeries do you perform per month?

aim: at least 3-5 per month for the vet personally. higher is better. lower (one or two a month) suggests less hands-on experience with rabbit-specific complications.

2. what anaesthesia protocol do you use?

aim: gas anaesthesia with isoflurane or sevoflurane. injectable-only protocols are higher risk.

3. is an IV catheter placed before induction?

aim: yes. allows immediate emergency drug administration if needed.

4. how do you maintain body temperature during surgery?

aim: active warming (heating pad, warm fluids). passive only is insufficient for rabbits.

5. do you use rabbit-specific monitoring equipment?

aim: yes, including capnograph for breathing assessment. capnograph reads expired CO2, which is more useful in rabbits than pulse oximetry alone.

if any of these answers concerns you, consider a different clinic. our vet directory lists exotic clinics with strong surgical protocols.

the rabbits at higher risk

higher anaesthesia risk for:

rabbits under 6 months
rabbits over 7 years
overweight rabbits (over body condition score 4 of 5)
rabbits with underlying conditions (respiratory issues, kidney function compromise, dental disease)
breeds with skull conformation issues (Netherland Dwarf, certain Lionhead lines)
rabbits who are stressed at intake

for these, ask about additional protocols: longer pre-op assessment, post-op monitoring, possible different drug choices.

the SG-specific situation

quality of SG exotic vet anaesthesia has improved significantly since 2020. several SG clinics now have:

dedicated rabbit/exotic surgical equipment
staff trained in exotic anaesthesia
capnograph and pulse oximetry on every surgical patient
proper warming systems
post-op observation areas

this is the gold standard. clinics still using only injectable anaesthesia and minimal monitoring exist; they tend to be older general clinics that occasionally treat rabbits.

the cost difference

higher-protocol anaesthesia costs more:

basic protocol with limited monitoring: spay quote $300-400
comprehensive protocol with full monitoring: spay quote $500-700
specialist exotic clinic with surgical board certification: spay quote $700-1000

the price difference often reflects equipment, staff training, and monitoring level. for healthy young adults, the basic protocol is acceptable. for higher-risk rabbits or major surgery, the comprehensive protocol is worth it.

what to expect on the day

morning of:

normal feeding 1 hour before drop-off
water available up to drop-off
bring familiar items (towel, hay)
arrive 30 minutes early for paperwork and consent

drop-off:

rabbit assessed by the vet team
IV catheter usually placed shortly after admission
pre-medication administered

during surgery:

you wait or go home; surgery typically takes 30-90 minutes for routine procedures
vet/clinic should call when surgery is complete
updates if anything unexpected occurs

pickup:

rabbit should be alert and warm
discharge instructions for home care
pain management plan, follow-up schedule
emergency contact for any concerns

post-op observation at home

first 24 hours are most critical:

rabbit should resume eating within 6-8 hours
droppings should resume within 12-24 hours
pain meds given as scheduled
monitor incision for swelling, discharge
contact vet if any concerns

beyond 24 hours, return to normal routine gradually over 5-10 days depending on procedure.

what owners often get wrong

three patterns:

shopping on price alone. the cheapest spay quote often skips the protocols that prevent complications. budget vs comprehensive isn’t optional for rabbits the way it sometimes is for cats and dogs
trusting clinics that don’t ask the rabbit-specific questions. if the consultation feels generic (same as a dog or cat consult), the protocol probably is too
fasting the rabbit. the rabbit must NOT fast. ever. if the clinic says to fast overnight, find another clinic — they may not handle rabbit-specific protocols
