A rabbit that hasn't eaten for more than 8–12 hours is at risk of GI stasis — a slowing or stopping of intestinal motility that can become life-threatening very quickly. Do not take a "wait and see" approach. Contact a vet who has rabbit experience today.
Why This Matters So Much
Rabbits are hindgut fermenters — their entire digestive system is designed to keep moving constantly. The cecum (a specialized part of their gut) contains trillions of bacteria that break down plant fiber. For this system to work, food must pass through continuously. When a rabbit stops eating, the gut slows, the bacterial balance shifts, gas accumulates, and the condition rapidly escalates. GI stasis is one of the most common causes of death in pet rabbits and it can develop from nothing to critical in under 24 hours.
Common Causes
Pain from another condition
Dental problems (overgrown teeth, dental spurs, tooth root abscesses) are the most common cause of rabbits going off food. If it hurts to chew, the rabbit won't eat. Other sources of pain — bladder stones, injury, arthritis — can also suppress appetite.
Stress
Significant stress — a new environment, moving home, a frightening experience, a new animal in the household, or extreme temperature — can cause a rabbit to stop eating. Even moderate stress can reduce appetite enough to trigger the beginning of stasis.
GI stasis itself
Stasis can begin the cycle — the rabbit eats less, the gut slows, gas builds, the discomfort suppresses appetite further. The condition becomes self-reinforcing.
Respiratory infection
Rabbits are obligate nose breathers and cannot breathe through their mouth. A blocked or congested nose from a respiratory infection can severely impact their ability to eat — they need their nose clear to smell and process food.
Signs to Check Right Now
- Are they producing droppings? Small, dry, misshapen, or absent droppings indicate gut slowing.
- Are they drinking?
- How is their posture? A hunched rabbit pressing their belly to the ground may be in pain from gas.
- Is their belly visibly bloated? Bloating alongside not eating is an emergency.
- Are they grinding their teeth? Tooth grinding in rabbits often indicates pain.
Veterinary Care
- Your rabbit has not eaten for more than 8 hours
- Droppings are absent, very small, or unusually dry
- Your rabbit is hunched, pressed against the floor, or grinding teeth
- Any visible belly bloating
- Your rabbit is lethargic and unresponsive to you
Find a vet with rabbit experience if possible — rabbit medicine is different enough from cats and dogs that specialist knowledge significantly improves outcomes. Many rabbit-savvy vets can provide gut motility medication, fluids, and pain relief that can turn stasis around quickly when caught early.
