I am pregnant and have been warned not to change my cats litter boxes, but they are indoor cats. I have gotten bottle babies who have had digestive issues but are on mediciene. I have read about toxoplasmosis but it says they only can get it from eating dead rodents. anyways their mother died i am unsure how as i got them from the animal shelter but they are about 2 weeks old. Could they carry the parasite? I do not want to catch it.
