This semester, I designed and participated in a praxis class entitled Abuse and Relocation in Shelter Environments. My field work takes place at PACCA, the Philadelphia Animal Care and Control Association. After working with dogs in a poorly funded shelter in Mérida, Mexico last year, I thought that I would be mentally prepared to launch myself into work in the U.S. However, what I discovered in Philadelphia is that cruelty towards animals in this country parallels the cruelty I found in Mexico. Every week, I see new evidence of abuse and neglect: starvation, scars, open wounds and overwhelming fear. I have learned about mange, pit-bull fighting, animal branding and pressure sores, which are abscesses that appear when a bone begins to protrude from the skin of an emaciated animal. As I conduct research about animal abuse and the people who commit it, I wonder where cruelty originates. Is there a template for cruelty laid down in the human brain? Is it something that is unique to our species? Why do human beings find pleasure in deliberately inflicting pain on other living things?
