A major Australian meta-analysis reviewing 17 studies found that childhood cat ownership is associated with double the odds of developing schizophrenia-related disorders. In this episode, we audit the data across 44 years of research to separate the biological risk from the statistical noise.
 
We cover:

• The "Toxoplasma" Hypothesis: How the parasite Toxoplasma gondii targets the central nervous system and alters dopamine levels.
• The Data: What the study of 11 countries actually proved (and what it didn't).
• Cat Scratch Disease: The potential role of Bartonella henselae bacteria in psychosis.
• Correlation vs. Causation: Why specific hygiene factors (like the litter box), not the animal itself, are the likely transmission vectors.

Don't panic—understand the biology to keep your family safe.

Key Topics: Schizophrenia Risk, Toxoplasma Gondii, Mental Health, Zoonosis, Bartonella, Cat Scratch Disease, Epidemiology.
