syringe-feeding a sick rabbit, the SG technique guide
a rabbit that stops eating is a rabbit on the clock. GI stasis kills in 24-48 hours if untreated. syringe-feeding while you wait for the vet (or while you’re treating at home under vet guidance) keeps the gut moving.
this is not optional skill. every rabbit owner should know it.
the product
Oxbow Critical Care is the standard. it’s a powder you mix with warm water to a thick milkshake consistency.
- Critical Care Anise flavour (most rabbits accept)
- Critical Care Apple-Banana
- emergency: blend high-quality pellets with warm water (less ideal)
keep a bag stored. it lasts 1-2 years sealed.
the mix
per serving:
- 1 part Critical Care powder
- 2 parts warm (not hot) water
- mix to thick smoothie consistency
- thick enough to stick to a spoon but flow through a syringe
- mix fresh, don’t store
the syringe
use a 10 ml curved-tip syringe if possible:
- the curved tip fits the side of the mouth
- 10 ml is the practical max per push
- some vets supply these
- pet shops stock them
the technique
steps:
- wrap rabbit in towel (burrito)
- sit on the floor, rabbit between your knees facing forward
- syringe goes in the SIDE of the mouth (diastema gap)
- behind the incisors, in front of the molars
- push 1-2 ml at a time
- wait for the rabbit to swallow before more
- if rabbit chews and swallows, great
- if rabbit lets it drip out, push slightly more
the schedule
a sick rabbit needs:
- 60-80 ml per kg of body weight per day, split across feedings
- a 2 kg rabbit: ~120-160 ml per day
- divided into 4-6 feedings throughout the day
example for 2 kg rabbit:
- 6am: 25 ml
- 10am: 25 ml
- 2pm: 25 ml
- 6pm: 25 ml
- 10pm: 25 ml
- (overnight if you can): 25 ml
the encouragement
between syringe feedings:
- offer fresh hay (rabbit may nibble)
- offer favourite greens
- offer pellets
- if rabbit voluntarily eats anything, reduce syringe feeding
- still monitor
the goal is to get the rabbit eating on its own again.
the SG-specific notes
three things relevant:
1. ambient temperature
- SG warm temps can dry out rabbit
- ensure water available between feedings
- syringe water if needed (separate from Critical Care)
2. emergency vet access
- syringe-feeding bridges to the vet, doesn’t replace
- 24-hour vets needed for stasis emergencies
- our emergency vet guide
3. observation between feedings
- droppings should restart within 12-24 hours of feeding
- if no droppings after 24 hours of feeding: urgent vet
- if rabbit refuses syringe: urgent vet
the warning signs
while syringe-feeding, escalate to vet immediately if:
- rabbit becomes lethargic or unresponsive
- temperature drops (cold ears)
- no droppings in 24 hours despite feeding
- bloated belly
- pain signs (grinding teeth, hunched)
- breathing changes
the recovery indicators
positive signs:
- rabbit voluntarily eats hay or pellets
- droppings restart
- gut sounds (gurgling on belly press)
- normal activity return
- normal posture
once eating voluntarily, taper syringe feeding over 2-3 days.
the hygiene
between feedings:
- clean syringes thoroughly
- replace if cracked
- store Critical Care sealed
- wash your hands
the multi-rabbit consideration
bonded pairs:
- keep them together (companion calms sick rabbit)
- syringe-feed sick rabbit
- monitor healthy one too (often eats less in sympathy)
what owners often get wrong
three patterns:
- waiting too long. within hours of stopped eating, start syringe-feeding
- not consulting vet. syringe-feeding is a bridge, not a cure
- giving up after rabbit fights. keep trying, the alternative is worse
