Meta-Analysis of 17 Studies in 11 Countries Links Cat Ownership to 2.24 Times Higher Schizophrenia Risk
Oct 24, 2024, 11:54 AM
A recent meta-analysis involving 17 studies from 11 countries has revealed a significant association between cat ownership and an increased risk of schizophrenia-related disorders. The research indicates that individuals who grew up with cats have 2.24 times higher odds of developing such disorders. While the findings suggest a correlation, the study also raises questions about causation, with some experts noting the possibility of reverse causation, where individuals with mental health issues may be more inclined to adopt cats for companionship. Conversely, another study highlights that living with cats may lower the risk of heart disease and stroke, suggesting a complex relationship between pet ownership and health outcomes.
