Conflict and affiliative behavior frequency between cats in multi-cat households: a survey-based study.

This is the first large-scale online survey to obtain frequencies of conflict and affiliative behaviors and compare them with factors linked to the cats or the home settings. The study confirmed that feline relationships are correlated with the owner's perceived impression of the initial introduction, but other household factors and cat population variables included in the study were not strongly predictive of the frequency of conflict or affiliative signs.
