Countries with more pet cats tend to be happier - study
A study found that countries with higher pet cat density tend to report higher levels of subjective happiness, based on an analysis of 93 countries. The researchers examined links between happiness, cat density and factors including GDP, income levels, healthcare spending and toxoplasma prevalence. Cat density showed a positive correlation with happiness, while IgM antibody prevalence showed a negative one. The authors said the findings show national-level correlations, not causation.
