An estimated 770,000 individuals in the U.S. experience homelessness,1 and an estimated 25% are accompanied by pets.2 Despite widespread stigma, there is limited empirical evidence about the health of pets owned by people experiencing homelessness and how it compares to other pet populations. Accordingly, this study aimed to compare the health of pets owned by unhoused individuals to that of low-income housed owners and unowned foster animals using a large dataset (n=910) of clinical records collected in Phoenix, Arizona
