The issue

Kathy Milani

HSI fights abuse and neglect of animals in their many forms. Recognizing the well-documented link between animal abuse and human violence, HSI works to pass animal welfare laws in countries that lack it, upgrade laws where legislation is weak, outlaw the most heinous practices involving animals, and train and assist government agencies in enforcement of those laws.

About abuse/neglect:

  • There is a well-established link between animal abuse and human violence, including domestic violence, child abuse, elder abuse and other violent crimes.
  • Animal protection needs worldwide span individual, group and institutional abuse.
  • Customs, laws and cultural traditions in different regions can pose challenges and require culturally sensitive navigation, methods and solutions to animal welfare concerns.
  • Some do not see animals as sentient beings who possess basic feelings, like loneliness, pain, fear and happiness.
  • Puppy mills remain a widespread, significant animal abuse and cruelty issue.
  • There are three types of animal hoarders: overwhelmed caregivers, rescuer hoarders and exploiter hoarders.
