I have 3 cats, but they all live indoors. Two of them haven't had their shots, and the youngest cat we have was adopted by us in June (6 months ago). I tested positive for toxoplasmosis, so my doctor ran another test to see if it's an active infection. Do all of my cats need to be tested for toxo? If I was exposed in June (6 months ago,) would there be any risk of infection passing to my 8 week old fetus? Thank you!
