The "Bambi effect" is an objection against the killing of animals that are perceived as "cute" or "adorable", such as deer, while there may be little or no objection to the suffering of animals that are perceived as somehow repulsive or less than desirable, such as pigs or other woodland creatures.[1]
Referring to a form of purported anthropomorphism,[2] the term is inspired by Walt Disney's 1942 animated film Bambi, where an emotional high point is the death of the lead character's mother at the hands of the film's antagonist, a hunter known only as "Man".[3][4][5]
