Female rabbits can make a squeaking sound if they are persistently mounted by either a male or another female, and this shows a degree of distress and anxiety and should not be ignored if it carries on for longer than a few days. The females in this film are sisters and the dominent sooty fawn female regularly mounted her sister, which caused her distress, and by the time foster carer Lisa had picked this pair up from their previous owners the situation had got to the stage where the dominant female only had to approach her sister for her to illicit this sound. Shortly after this film was made (filmed by Lisa, in the nest box of their pen) the sisters were separated, spayed, and each bonded with a neutered male.
