Cats appear to grieve death of fellow pets – even dogs, study finds
A study suggesting that cats mourn the death of companion animals, including dogs, prompts wide-ranging debate on what non-human animals actually understand about death and loss. Commenters share anecdotes of pets pacing, crying, searching the house, or becoming withdrawn after another pet dies, while others caution against anthropomorphism and question whether these behaviors reflect grief or simple confusion over absence. The exchange raises broader questions about animal cognition, evolutionary reasons for social bonding and mourning, and how humans interpret and respond to their pets’ emotional lives.
Concept of Death vs. Absence
- Many argue cats likely distinguish “gone for now” from “gone for good,” especially after seeing/smelling a body; searching often stops afterward and behavior shifts to lethargy or clinginess.
- Others doubt cats grasp an abstract, human-like “concept of death,” suggesting they mainly perceive absence, changed smell, and non-responsiveness.
- Several note that being predators or killers does not automatically imply an abstract understanding of death.
- Debate centers on definitions: is grief about understanding death, or about distress after a major loss regardless of cognition?
Anecdotal Evidence of Grief (and Non-Grief)
- Numerous stories of cats and dogs:
- Searching the home, vocalizing, checking favorite spots.
- Reduced appetite, excessive grooming, lethargy, heightened need for human contact.
- Some pets visibly distressed until a new companion arrives.
- Some opposite anecdotes: survivors appear indifferent or even more relaxed and outgoing after another pet dies, possibly due to reduced competition or increased human attention.
- Reports extend beyond pets: farm animals, squirrels, and other species behaving as if distressed by a companion’s death or disappearance.
Anthropomorphism, Projection, and Memory
- Several commenters worry owners project human emotions onto pets, especially when grieving themselves.
- Others respond that while animal experience is different, their emotional lives are clearly complex and not well captured by dismissing it as projection.
- A theme: humans grieve heavily via reflection on past and future, whereas animals may be more present-focused, so their grief may be different in quality.
Evolutionary and Methodological Questions
- Some expect grief-like responses to be widespread in social mammals because strong attachment is adaptive; grief may be a byproduct of attachment mechanisms.
- Others say the evolutionary value of grief (even in humans) is unclear and need not be positive.
- Methodological concerns about the cited study: reliance on owner surveys during emotional periods, lack of strong controls, and difficulty objectively measuring animal emotions.
Practical Approaches and Broader Ethics
- Multiple commenters advocate letting surviving pets see/smell deceased companions, often reporting less searching afterward.
- At-home euthanasia is highlighted as less stressful and better for both humans and animals.
- Some use the discussion to question human treatment of non-pet animals, given evidence of widespread animal emotional capacity.
