The death of a companion animal causes profound grief in many owners, and animals themselves show behavioral responses to the loss of bonded companions that suggest they too experience grief.
Companion animal grief affects both the human owner and surviving animals in the household. Dogs may search repeatedly for a missing companion, refuse food, and show changes in sleeping patterns. Cats may become withdrawn or unusually clingy. These behavioral signs are consistent with a grief-like response, though interpreting animal emotion requires care. For humans, disenfranchised grief — grief not recognized as legitimate by society — can complicate recovery. Acknowledging the full emotional significance of companion animal loss, and supporting both human mourners and surviving animals, is an important dimension of companion animal welfare.
