Signs of a Sick Rabbit at a Glance
Rabbits evolved as prey animals that cannot show weakness. By the time symptoms are obvious, the condition is often advanced.
Symptom Urgency by Severity
Rabbit Symptoms & What They Mean
| Symptom | What It May Mean | Urgency | Action |
|---|---|---|---|
| Not eating 12+ hours | GI stasis, dental pain, stress | Emergency | Vet immediately |
| Small or no stool | GI stasis or blockage | Emergency | Vet immediately |
| Loud teeth grinding | Significant pain | Emergency | Vet immediately |
| Sneezing/nasal discharge | Respiratory infection (snuffles) | High | Vet within 24 hours |
| Head tilt / circling | Ear infection or E. cuniculi | Emergency | Vet immediately |
| Hair loss / scratching | Mites, fur mites, or adrenal issue | Moderate | Schedule vet |
| Soft stool/diarrhea | Diet issue, parasites, dysbiosis | High | Vet within 24 hours |
| Eye discharge / squinting | Dental abscess (root), conjunctivitis | Moderate | Schedule vet |
| Weight loss (gradual) | Dental disease, chronic illness | Moderate | Schedule vet |
| Sudden aggression | Pain, hormonal, or vision loss | Moderate | Check with vet |
Daily Rabbit Health Check
| Check that your rabbit is eating, drinking, and producing normal droppings daily | |
| Feel for a normal body temperature (101-103°F) — cold ears = emergency | |
| Weigh your rabbit weekly — any weight loss warrants investigation | |
| Look at teeth alignment (if rabbit will tolerate it) for signs of malocclusion | |
| Monitor breathing — should be quiet and effortless, not labored or noisy | |
| Never assume 'a rabbit who stops eating will start again' — this kills rabbits daily | |
| Do not give over-the-counter pain meds — many are toxic to rabbits | |
| Don't skip the 12-hour rule — 12 hours without food = emergency, period | |
| Never wait until morning — rabbits deteriorate faster than cats or dogs |
A rabbit that stops eating for 12 hours is in danger. For 24 hours, the survival rate drops significantly. Time is the most critical factor.
Check your rabbit's droppings daily — they are the single best health indicator. Normal droppings are round, dry, and plentiful. Any change is a red flag.
Signs Your Rabbit Is Sick: When to See a Vet
Rabbits are prey animals, which means they instinctively hide signs of illness — a survival mechanism that makes it harder for owners to notice problems early. By the time a rabbit appears visibly sick, the condition may already be serious. This guide covers the warning signs to watch for and what they might indicate.
🚨 Emergency Signs — Vet Same Day
- Not eating or drinking for 8+ hours
- No droppings for 8+ hours
- Sudden drastic behavior change
- Labored or noisy breathing
- Head tilting to one side (head tilt)
- Seizures or loss of balance
- Swollen, distended abdomen
- Inability to move hindquarters
Rabbits can deteriorate within hours. Do not wait to see if it improves.
Warning Signs to Watch For
Changes in Eating and Drinking
A healthy rabbit eats constantly throughout the day. Any deviation is a red flag:
- Not eating hay: The most serious sign — hay is essential for gut motility. Could indicate GI stasis, dental pain, or illness.
- Not eating pellets or greens: Less urgent but warrants monitoring; if combined with other signs, see vet.
- Increased water intake: Could indicate kidney disease or diabetes (rare in rabbits but possible)
Changes in Droppings
Rabbit droppings are an excellent health indicator. Check them daily:
- No droppings: GI stasis — emergency
- Small or misshapen droppings: Slowed gut motility; monitor closely
- Diarrhea (liquid cecotropes): May indicate diet imbalance, stress, or infection; also may be cecotropes left uneaten (dietary issue)
- Droppings covered in mucus: Intestinal problem; see vet
Behavioral Changes
- Teeth grinding (bruxism): Soft purring-like grinding = contentment. Loud, visible grinding = pain.
- Hunched posture: Belly pain or discomfort
- Hiding more than usual: Stress, illness, or pain
- Lethargy: A rabbit that isn't binkying, running, or exploring may be ill
- Aggression in a previously calm rabbit: May indicate pain, hormonal issue, or illness
Physical Signs
- Head tilt: Emergency. Causes include inner ear infection (pasteurella), parasitic infection (E. cuniculi), or stroke.
- Runny eyes or nose: Snuffles (pasteurella), dental disease (roots press on tear ducts), or other respiratory issues
- Wet chin: Dental disease causing excessive drooling
- Bald patches or excessive scratching: Mites, ringworm, or barbering (stress)
- Swollen jaw: Dental abscess — requires veterinary treatment
- Urine staining on hindquarters: May indicate inability to groom (arthritis in older rabbits) or urinary issues
GI Stasis: The Silent Killer
Gastrointestinal stasis is when the digestive system slows or stops. It's one of the most common causes of rabbit death, and it can kill within 24–48 hours if untreated.
Signs of GI stasis:- Not eating (especially not hay)
- No or very few droppings
- Hunched posture, teeth grinding
- Gurgling or silent belly (no gut sounds)
- Bloated or hard abdomen
This is an emergency. Go to a vet immediately. Do not wait overnight to see if it improves.
Daily Monitoring Checklist
- ✅ Eating hay (constantly)
- ✅ Normal droppings (plentiful, round, firm)
- ✅ Active and alert at normal times
- ✅ Normal posture (not hunched)
- ✅ Clear eyes and nose
- ✅ Eating cecotropes (you may rarely see this — they do it directly)
