Cats can experience grief-like responses following the loss of a companion — whether another cat, a dog, or a human — and these responses represent genuine welfare concern. While scientific debate about the nature of animal grief continues, behavioural observations strongly suggest that cats experience something functionally analogous to grief following significant losses.
Signs of Feline Grief
Common behavioural changes observed in cats after losing a companion:
Searching behaviour: visiting places associated with the deceased companion, vocalising at those locations
Reduced appetite and eating
Increased vocalisation or unusual quietness
Changes in sleeping patterns or locations
Reduced activity and social engagement
Changes in grooming (reduced or excessive)
Withdrawal or increased clinginess
These signs typically peak in the first weeks and gradually resolve, though some cats show prolonged responses lasting months.
Supporting a Grieving Cat
Maintain routine: consistency in feeding times, play, and interaction provides stability
Increase quality human interaction: additional play sessions and companionship
Don't rush into getting a new companion: introduce a new cat only when the grieving cat has stabilised, and manage introduction carefully
Allow access to places associated with the lost companion rather than blocking these
Monitor appetite and body condition: reduced food intake for more than 2-3 days warrants veterinary attention
Veterinary support: if grief responses are prolonged or severe, short-term anxiolytic medication may help
Human-Cat Bond & Human Grief
The death of a companion cat also causes genuine grief in owners. The veterinary team has an important role in supporting owners through this process. Pet bereavement support services are available through animal charities and some veterinary practices. Recognising the depth of the human-animal bond and validating owner grief is an important component of compassionate veterinary care.
