Signs of Illness in Rabbits

Introduction

Because rabbits instinctively hide weakness, signs of illness can be subtle until a condition becomes serious. Knowing the signs of illness in rabbits — and acting quickly when you spot them — is one of the most important skills a rabbit owner can develop. Here's a comprehensive reference guide.

Digestive Warning Signs

The digestive system is the most common source of illness in rabbits. Any change in eating or bathroom habits should be taken seriously.

• Not eating hay — The most serious sign. A rabbit that stops eating hay needs veterinary attention within hours.
• Reduced or absent droppings — Fewer droppings, smaller droppings, or no droppings at all indicate a digestive slowdown.
• Soft cecotropes — Mushy droppings stuck to the fur around the bottom; often caused by diet imbalance.
• Diarrhea — True watery diarrhea (not soft cecotropes) is a medical emergency, especially in young rabbits.
• Bloated belly — A hard, distended abdomen indicates dangerous gas buildup.
• Gut sounds — Loud gurgling or complete silence when listening to the belly are both warning signs.

Behavioral Warning Signs

• Hunched posture — A rabbit sitting hunched with eyes half-closed is in pain
• Tooth grinding (bruxism) — Loud grinding indicates significant pain; soft tooth purring is normal contentment
• Hiding more than usual — Sick rabbits retreat and become less interactive
• Sudden aggression — Pain can cause normally gentle rabbits to bite or lunge
• Loss of interest in food, toys, or surroundings — A rabbit that ignores their favorite treats is unwell

Physical Warning Signs

• Nasal discharge — White or yellow discharge from the nose ("snuffles") indicates respiratory infection
• Eye discharge — Crusty or watery eyes can indicate infection or dental problems
• Head tilt — Can indicate inner ear infection (otitis) or E. cuniculi (a parasitic infection)
• Wet chin or drooling — Almost always indicates dental problems (tooth spurs or malocclusion)
• Hair loss — Can indicate mites, ringworm, or hormonal issues
• Sore hocks — Red, raw, or ulcerated skin on the bottom of the feet
• Limping — Can indicate injury, arthritis, or sore hocks
• Weight loss — Gradual weight loss is often the first sign of chronic illness

Respiratory Warning Signs

• Rapid or labored breathing
• Open-mouth breathing (always an emergency)
• Clicking or wheezing sounds when breathing
• Blue-tinged gums or lips (oxygen deprivation — emergency)

Urinary Warning Signs

• Straining to urinate
• Cloudy or white-tinged urine (calcium sludge)
• Blood in urine (can be normal in does but warrants investigation)
• Urine scald — wet, red, or raw skin around the genitals from urine contact
