Passive cruelty is typified by cases of neglect, in which the cruelty is a lack of action rather than the action itself. Examples of neglect are starvation, dehydration, parasite infestations, allowing a collar to grow into an animal’s skin, inadequate shelter in extreme weather conditions, and failure to seek veterinary care when necessary. In many cases of neglect in which an investigator believes that the cruelty occurred out of ignorance, the investigator may attempt to educate the pet owner, then revisit the situation. In more severe cases, exigent circumstances may require that the animal be removed for veterinary care.
