My first question would be: or is it that cat owners are schizophrenic are more likely to get a cat?
I'm not answering that question, but I do want to quote your article. From the bottom:
> Results were inconsistent across studies, but those of higher quality suggested that associations in unadjusted models might have been due to factors that could have influenced the results.
> One study found no significant association between owning a cat before age 13 and later developing schizophrenia, but it did identify a significant link when narrowing down cat ownership to a specific period (ages 9 to 12). This inconsistency suggests that the critical window for cat exposure is not well defined.
> A study in the US, which involved 354 psychology students, didn't find a connection between owning a cat and schizotypy scores. However, those who had received a cat bite had higher scores when compared to those who had not.
> Another study, which included people with and without mental disorders, discovered a connection between cat bites and higher scores on tests measuring particular psychological experiences. But they suggested other pathogens, such as Pasteurella multocida, may be responsible instead.
> Before we can make any firm interpretations, the researchers reiterate that we need better and broader research.
And of course there's endless correlation-causation isseus there as well. Under most circumstances you have to be both aggressive and careless to get bitten by a cat in the first place.
