The loss of a pet or an animal to which one has become emotionally bonded oftentimes results in grief[1] which can be comparable with the death of a human loved one, or even greater, depending on the individual. The death can be felt more intensely when the owner has decided to end the pet's life through euthanasia.[2] While there is strong evidence that animals can feel such loss for other animals,[3] this article focuses on human feelings when an animal is lost, dies, or otherwise is departed.
