The most common saying that cats can't keep cats is that cats have bacteria, which can easily lead to miscarriage. People who know more say that cats have Toxoplasma gondii, which will have a serious impact on the fetus. But this statement is not correct. Toxoplasma gondii will enter the fetus through the placenta, resulting in congenital malformation of the fetus, affecting the nervous system and chorioretinal system of the baby, causing chorioretinitis, leading to microcephaly and aphasia. More serious infections can cause diseases such as hydrocephalus and intracranial calcification, so prospective fathers should have an examination before pregnancy. If the expectant mother is Toxoplasma antibody positive, then he must be infected with Toxoplasma gondii, so it is necessary to prevent and treat it in time. At this time, the cats at home should also be checked. If you have a cat pet, you should take precautions in time. If you haven't had a cat before, it is recommended that expectant mothers don't have one after pregnancy. For the existing cats, it is necessary to vaccinate her regularly and do a good job of deworming. When in contact with cats at ordinary times, expectant mothers should not clean up the cat's feces or get too close to the cat to avoid contracting toxoplasmosis.
