"Based on the results of this study, the authors concluded that cats do not appear to attach to their owners as a focus of safety and security ("secure base") in the same way that dogs do to their owners, or children to their parents. The behaviors chosen to evaluate attachment in the SST may not be biologically relevant given the cat's nature as an independent, solitary hunter. This nature may determine that a cat's relationship with its owner does not have to (but still might in the case of some individuals) involve a perception of the owner as a safety and security attachment focus. The authors hypothesize that in those cats in which separation-related problems are identified, there could be a classical attachment bond to the owner, but it is more likely that such problems are a response to frustration at owner absence. Further research is required to test this hypothesis."
