When a bonded rabbit loses their companion, they often grieve intensely. Understanding this process helps owners support surviving rabbits and successfully introduce new companions.
Grief in rabbits is a genuine welfare concern backed by behavioral evidence. A rabbit who has lost their bonded partner may stop eating, become lethargic, or develop gastrointestinal stasis from stress — all of which require veterinary attention. Rushing a new bond before the surviving rabbit has emotionally stabilized can cause further stress. Shelters that allow grieving rabbits to "meet" potential new companions in neutral territory, with patience for the bonding process, report the best outcomes for long-term welfare.
