Anaemia in rabbits

Quick answer

**Anaemia is dangerously low red blood cells.** Pale gums, weakness and fast breathing are emergency signs in rabbits. A common UK cause in young rabbits is **flea or mite blood loss** — but gut bleeding and uterine disease also occur. Phone your **rabbit-savvy vet the same day**.

Key takeaways

  • Anaemia is a low red blood cell count or low haemoglobin. Red cells carry oxygen — without enough, rabbits become weak, breathe faster and may collapse.
  • Common causes include blood loss from fleas or mites (especially in young rabbits), gut bleeding, uterine disease in unspayed females, chronic disease, and bone marrow problems.
  • Signs include pale gums and inner eyelids, weakness, lethargy, fast breathing, reduced appetite, and collapse. Pale gums in any rabbit need same-day vet assessment.
