Enrichment for rabbits must be grounded in understanding of their natural behaviour. Wild rabbits (Oryctolagus cuniculus) are crepuscular (most active at dawn and dusk), highly social, live in burrow systems, travel several kilometres daily, and engage in complex social hierarchies. Companion rabbits retain these behavioural drives regardless of domestication.
Traditional hutch sizes are wholly inadequate for rabbit welfare. Current guidance (RWAF/PDSA) recommends a minimum combined living and exercise space of 3m x 2m x 1m, allowing rabbits to perform their natural movement repertoire: binkying (jumping and twisting), digging, running, and standing fully upright. Permanent or large-run access is strongly preferred over restricted hutch-plus-run combinations.
Digging is a powerful behavioural drive in rabbits. Providing a digging area (deep box of soil, sand, or child-safe play sand) significantly reduces stereotypical digging at enclosure walls and allows expression of natural behaviour. Tunnels and hiding areas mimic the burrow system and provide psychological security.
Rabbits are highly social and should ideally be kept in bonded pairs or compatible groups. Solitary housing causes chronic stress. Human interaction, while valuable, does not replace conspecific companionship. Bonding two rabbits requires a careful introduction process; neutering both animals reduces aggression and facilitates bonding.
Signs of enrichment deprivation and chronic stress in rabbits: bar-chewing, repetitive circling, excessive thumping, aggression, fur pulling, obesity, dental disease (linked to low-hay diets), and flystrike (linked to reduced movement and obesity). Many of these signs are normalised by owners unfamiliar with good rabbit welfare.
