There could be any number of reasons why your rabbit may not want to play. In some cases, a lack of stimulation can lead to behavioural issues such as antisocial behaviour or hypersensitivity. If contact is restricted to certain areas of the hutch – for example, if they are kept in an area with only one or two toys instead of a wide variety – this can also lead to boredom and anxiety. If your rabbit starts playfully chasing or biting you when you reach out to them, it may be time to consider changing their environment.
