I have a bunny who is almost 4 months old. she has never had a panic attack until today. she was sitting in her cage and I was in my room and I was sitting in bed and all of a sudden I see my bunny running around her cage slipping and falling on her back. this was about 10 seconds and I ran to her cage to pet her and she calmed down and acted normal again. does anyone know what happened and if that was a panic attack? also there werent loud noises in the house everything was calm
