Abstract
Introduction: People can be rejected by friends, strangers, hated outgroups, or computer simulations. The present research examines whether people can be rejected by pets.

Methods: Two studies examined whether people can feel rejected by pets and how this affects their mood, fundamental needs, and aggression. Participants in Study 1 were directly rejected by a pet using an adapted version of the video message paradigm, and then reported on their mood, fundamental needs, and aggression. Study 2 directly compared differences in needs when writing about a rejection experience by a pet, a rejection experience by a person, and a control experience.

Results: Study 1 confirmed that people can feel rejected by their pets by demonstrating that those who were rejected felt more negatively and less positively and had decreased need satisfaction, however they did not experience any changes in their aggression. Finally, in Study 2, people who were rejected by a pet or by a person experienced decreased need satisfaction as compared to a control experience.

Discussion: Ultimately, these studies confirm pets can be perpetrators of rejection and such rejection hurts similarly to if a human perpetrated it. This may add to the growing body of research suggesting that pets do not provide uniformly positive effects on people.
