Rabbit Facts # 33 - Rabbits Cannot Vomit
Domestic rabbits physically cannot vomit because of key anatomical features in their digestive system. The main reason is their extremely strong cardiac sphincter muscle between the esophagus and stomach, which acts as a one-way barrier allowing food and liquids to enter the stomach, but making it virtually impossible for anything to move backward into the esophagus and out through the mouth. Additionally, their diaphragm is relatively weak, which means they lack the muscular strength and control required for the forceful contractions involved in vomiting, a process seen in many other mammals.
➡️ Rabbit Digestive Anatomy
🔸The cardiac sphincter is particularly robust in rabbits, preventing reverse movement of food and fluids.
🔸Rabbits do not possess a gag reflex, further limiting their ability to purge stomach contents.
🔸Their esophageal muscles only move food in one direction—from mouth to stomach—unlike some animals that can reverse this process
➡️ Implications for Rabbit Health
🔸Rabbits cannot expel toxins or indigestible material by vomiting, making them especially vulnerable if they ingest something harmful or develop blockages such as hairballs.
🔸Symptoms mistaken for vomiting—such as choking, coughing, or fluid leaking from the mouth—ARE NOT TRUE VOMITING AND REQUIRE IMMEDIATE VETERINARY ATTENTION.
🔸Digestive issues in rabbits often present as changes in appetite, energy level, and f***l output, rather than vomiting
