Rabbits are grazing animals built to keep fibre moving through the gut almost every waking hour. When that movement slows or stops, the condition is called gastrointestinal stasis, and it is one of the few small-pet problems where a delay of a few hours genuinely changes the outcome. Because rabbits are prey animals, they hide discomfort well, which is why the most useful tool you own is an evening check of what went in and what came out.
Why the overnight hours matter
Stasis is self-reinforcing. As gut movement slows, gas builds and the stomach and cecum stretch. That distension hurts, pain suppresses appetite further, and the gut slows again. Meanwhile a rabbit that is not eating has almost no energy reserve, so the liver can begin to accumulate fat within a day or two. The classic hairball is usually a result of the slowdown, not the cause of it.
Stasis is also almost always secondary. Dental pain, dehydration, stress, urinary discomfort, arthritis, a sudden diet change or a true obstruction can all start it. That is why home remedies cannot tell you what is actually happening, and why the goal of an overnight watch is to reach a rabbit-savvy vet early rather than to treat at home.
What to check before bed
Learn your own rabbit’s normal first. A healthy adult eats hay in bursts through the day and leaves a steady supply of round, dry pellets. Once you know that baseline, changes stand out immediately.
- Hay and greens: did it finish the evening hay, or turn away from a favourite green?
- Water: a sudden drop in drinking often appears before droppings change.
- Litter box: pellet count, size and shape. Smaller, drier or string-linked pellets are an early signal.
- Posture: a rabbit pressed into a hunched ball, belly tucked, eyes half closed, is uncomfortable, not just resting.
- Teeth: loud, crunching grinding is pain. Soft purring while being stroked is contentment.
- Belly and bottom: a tight, drum-like abdomen, repeated uneaten cecotropes, or a messy rear all need attention.
The twelve-hour rule
If a rabbit has not eaten and has not passed droppings for around twelve hours, treat it as an emergency and contact a rabbit-experienced vet immediately. Do not wait for morning to see whether it improves. The table below is a rough guide to urgency, not a replacement for veterinary advice.
| What you notice | How urgent |
|---|---|
| Favourite greens refused, but hay still nibbled | Call the vet today; keep observing closely |
| Fewer, smaller or drier droppings | Same-day vet call |
| Hunched posture, no droppings, loud tooth grinding | Emergency, go now |
| Bloated abdomen, cold to the touch, weak or unresponsive | Emergency, and keep the rabbit warm in transit |
What not to do overnight
Good intentions cause real harm here. Do not syringe-feed a rabbit that is bloated, weak or unable to swallow; aspiration and worsening gas are genuine risks. Do not give human painkillers, leftover medication, laxatives or gas remedies on your own judgement, and never attempt an enema or press on the belly. Do not force a painful rabbit to exercise as a substitute for care.
While you arrange transport, keep the rabbit calm in a carrier with a soft towel, away from noise and other pets. Offer fresh hay and water in a bowl if it is willing. If it feels cold, warm it gradually with a wrapped heat pack placed beside the carrier, never directly underneath.
Building a rabbit that resists stasis
Unlimited grass hay stays the centre of the adult diet, with pellets and greens as a measured supplement rather than the main event. Keep feeding times predictable, change foods slowly, and give enough space to move, since movement stimulates gut motility. A recurring stasis episode means something upstream is still unresolved, so ask for dental and pain assessments rather than treating the gut again and again.
Finally, know where the nearest rabbit-savvy clinic is before you need it and keep the carrier ready. The overnight check takes five minutes, and it is the cheapest insurance a house rabbit will ever have.
