Jaundice in Rabbits: Yellow Skin, Yellow Eyes, and Liver Disease

Jaundice, also called icterus, means yellow pigment has built up in the body. That pigment is bilirubin, a substance made when red blood cells are broken down. When bilirubin rises high enough, it can stain the skin, gums, ears, sclera of the eyes, and other pale tissues yellow. In rabbits, this is always a sign that something important is going wrong.

Jaundice is not a final diagnosis. It is a visible clue that your rabbit may have liver disease, inflammation affecting the liver or bile system, severe infection, toxin exposure, or a problem that is destroying red blood cells faster than the body can handle. Merck notes that jaundice reflects abnormal bilirubin accumulation in the circulation and tissues, while rabbit references also note that severe hepatic lipidosis can develop when a rabbit stops eating and may require aggressive nutritional support.

Because rabbits are prey animals, they often look only mildly sick at first. A rabbit with jaundice may still be sitting quietly, but underneath that calm appearance there may be dehydration, pain, gut slowdown, liver dysfunction, or shock. That is why yellow discoloration in a rabbit should be treated as an emergency sign rather than a wait-and-see problem.

Jaundice develops when bilirubin builds up faster than the body can clear it. That can happen for three broad reasons: the liver is damaged and cannot process bilirubin well, bile flow is impaired, or red blood cells are being destroyed too quickly. In rabbits, liver-related causes are often the biggest concern.

One important cause is hepatic lipidosis, sometimes called fatty liver. Rabbits can develop this after even a short period of poor appetite, stress, pain, obesity, or another illness that makes them stop eating. Merck’s rabbit guidance notes that severe hepatic lipidosis may require active assisted feeding, including syringe feeding or tube feeding in some cases. GI stasis and anorexia can also be tied to underlying liver disease, creating a dangerous cycle.

Other possible causes include severe bacterial or systemic infection, inflammatory liver disease, toxin exposure, and less commonly diseases that damage red blood cells. Infectious rabbit diseases can also affect the liver. VCA and Cornell both describe rabbit hemorrhagic disease as a condition that can involve severe liver injury or liver failure, though this disease usually causes sudden, critical illness rather than a mild chronic yellowing.

Your vet may also consider cancer, abscesses, bile duct problems, or advanced multisystem illness. The exact cause matters because treatment is aimed at the underlying problem, not the yellow color alone.

Your vet will start with a full history and physical exam. Helpful details include when your rabbit last ate normally, whether droppings have changed, any recent weight loss, access to toxins or new plants, exposure to other rabbits, and whether there has been stress, pain, or recent illness. In rabbits, even a short period of anorexia can be medically important.

Bloodwork is usually the next step. This may include a complete blood count to look for anemia or infection and a chemistry panel to assess bilirubin, liver enzymes, kidney values, glucose, and electrolytes. VCA notes that rabbits with GI stasis often show dehydration and may also have bloodwork changes linked to underlying liver disease.

Imaging is often needed because jaundice rarely tells the whole story by itself. X-rays can help look for gut stasis, organ enlargement, or other abdominal changes. Ultrasound can give more detail about the liver, gallbladder region, masses, fluid, or other internal disease. In some cases, your vet may recommend bile acids testing, clotting tests, infectious disease testing, or sampling of liver tissue if the rabbit is stable enough.

Diagnosis in rabbits is often a process of narrowing possibilities while stabilizing the patient at the same time. If your rabbit is weak, cold, dehydrated, or not eating, supportive care may begin before every answer is available.

You cannot prevent every cause of jaundice, but you can lower risk by protecting your rabbit’s liver and overall health. The biggest day-to-day step is helping your rabbit keep eating normally. A high-fiber diet centered on grass hay, measured pellets, fresh greens your vet approves, clean water, and regular weight checks can help reduce the risk of obesity, gut slowdown, and secondary hepatic lipidosis.

Because rabbits can become very sick after even a short period of poor appetite, treat appetite loss as urgent. If your rabbit skips meals, produces fewer droppings, seems painful, or hides more than usual, contact your vet early rather than waiting for yellowing to appear. Fast action may prevent a mild problem from turning into liver injury.

Good prevention also includes safe housing and toxin awareness. Keep rabbits away from unsafe plants, human medications, pesticides, moldy feed, and household chemicals. Routine wellness visits matter too, especially for senior rabbits or rabbits with dental disease, chronic GI issues, or weight problems.

If rabbit hemorrhagic disease is a concern in your area, ask your vet about vaccination, quarantine for new rabbits, and biosecurity steps. Infectious liver disease is not the most common reason a pet rabbit becomes jaundiced, but it is one more reason to stay current with preventive care.
