Finally, though we chose the study design to control for confounding variables, its simplicity may have made our research objective too obvious to respondents.

Regardless, given the educational status of our sample, we cannot rule out the potential that some of the respondents were biased by guesses as to the purpose of the study.
I don't think it's because cats make men look less masculine I think it's just because cats are horrible creatures. They're brood parasites with 0 care for humanity other than as a host so most people wouldn't wanna have to deal with one should they become a couple and move in together in the future.
