Few studies have examined childhood and adolescent animal cruelty motives. Using a sample of 261 inmates surveyed at both medium and maximum security prisons in a southern state, the present study examined the impact of demographic attributes and situational factors relating specifically to a range of animal cruelty motivations. Almost half of the inmates who engaged in animal abuse reported committing some of the acts out of anger, whereas more than a third did so for fun. Regression analyses revealed that the most statistically salient variable in 7 of the 10 motivational models was whether animal cruelty was committed alone. Respondents who reported hurting or killing animals alone were more likely to commit the acts out of anger but less likely to have committed them to impress others, for sex, or to imitate others.
