Cats show grief responses after losing bonded companions, and owner recognition and support during bereavement prevents prolonged welfare compromise.
Cat grief is a welfare reality that has historically been dismissed but is now supported by behavioural evidence. Cats who have lost bonded companions show measurable behaviour changes consistent with distress, including altered eating, sleeping, and activity patterns. Owner awareness allows proactive welfare support: maintaining routine, providing increased positive human interaction, and monitoring for signs of prolonged depression requiring veterinary assessment. The timing of introducing new animals requires careful judgment; too early may compound stress, while too late prolongs social isolation for a social cat. Recognising and responding to cat grief dignifies the genuine emotional capacity of these animals.
