What makes a pet rabbit all a sudden do flip and fall over?

When a pet rabbit suddenly does a flip and falls over, it can be a sign of a behavior known as "binky." Binkies are joyful leaps and twists that rabbits perform when they are happy and playful. However, if the rabbit falls over and appears disoriented or lethargic, it could indicate a health issue, such as a neurological problem or an ear infection. In such cases, it's essential to consult a veterinarian for proper evaluation and care.
