Small birds and mammals are often injured by dogs and cats. Some of these animals are brought to the wildlife rehabilitation centers. The number of admitted animals varies seasonally, and dogs and cats can have different effects on animals in different life stages. This study looked at 9,696 records of small birds and mammals admitted to a wildlife center in the Upper Midwest (Wisconsin) between 2014 and 2017. Data regarding taxon, species, date of admission, life stage, circumstance of rescue, and outcome were compared between dogs and cats. Data from dog and cat interactions were also compared to other causes for admission.
