Psychology says people who adopt strays and give a home to abandoned animals aren't simply making a decision based on random pity or impulse. Their behaviour can involve empathy, compassion, emotional connection and a sense of responsibility toward vulnerable animals. A person may feel connected to an animal that has been injured, abandoned, frightened or rejected. This connection can encourage the person to provide food, shelter, medical care and a permanent home. Research on pet rescue and adoption also points to the role of previous experience with animals, emotional responses to suffering and a willingness to help. The behaviour can also create a bond that benefits both the animal and the person.
