Ristau, Carolyn A. (2017) Self, death, and suicide: Does an animal know of these?. Animal Sentience 20(5)
David M. Peña-Guzmán, Can nonhuman animals commit suicide?
Peña-Guzmán makes a strong case, using examples from the media and scientific literature, that many captive animals suffer severely. In examining the possibility of animal suicide, he dismisses the need for “reflective self-subjectivity” and “intent” in suicidal behavior. He claims that at least some animals understand “death,” citing examples of behavior he deems to be death “rituals.” But these can be more simply interpreted. The possibility of animal suicide remains more dubious than Peña-Guzmán suggests.
