Been digging on rh +/- blood types and found research data thats actionable for your odds to stay in the gene pool.
Conclusion: if you have (-) blood types, dont have cats.
If you are rh-, your reaction times will be 20% slower if you catch the cat lady pathogen.
If you are Rh+ you are resistant to the reaction time effect of the toxoplasmosis
