This study aimed to investigate differences and similarities of the pet–owner relationship and management of dogs and cats living in the same household. An online survey was completed by 1270 individuals who owned both dog(s) and cat(s). Most of the respondents owned only one dog (56.4%) but two or more cats (63.1%; p p p p p p p p p p < 0.05) and allowing dogs and cats to sleep in the owners’ bedroom were associated with a stronger perceived pet–owner bond. Implications for cat and dog welfare are discussed.
