Rabbits have limited vocalizations, but their sounds can communicate different things:
Grunting or Snorting: Often a sign of contentment.
Thumping: A warning of fear or danger.
Teeth Grinding: Can indicate pain, discomfort, or relaxation during grooming.
Chirping or Clicking: Soft communication between bonded rabbits or a sign of happiness.
Screaming or Yelping: Extreme pain or fear.
Pay attention to your rabbit's overall behavior and body language to understand its communication better.
