Phlegm-Like Discharge in a Pregnant Bunny Is Not Normal
It is not normal for a pregnant rabbit to excrete a phlegm-like substance. Pregnancy itself does not cause phlegm production, and this symptom could signal a serious health problem.
Possible Causes
A phlegm-like substance may indicate a respiratory infection such as pneumonia or a lung abscess, which are especially dangerous for pregnant rabbits. It could also result from digestive issues, injury, or a foreign object in the throat.
What to Do
Consult a veterinarian immediately. Isolate the pregnant bunny from other rabbits to prevent potential infection spread, and monitor her behavior, appetite, breathing, and energy levels closely. Report any changes to your vet.
Pregnant rabbits are especially vulnerable, so early veterinary intervention is critical.
