Hello, i am a 21 years old girl and i was thinking of having a cat however i heard that it is harmful for the woman's eggs and blood...is this true?

Enjoy your pet: There is a condition called toxoplasmosis that can be acquired by humans who are exposed to the fecal material of infected cats. If this is experienced during pregnancy, the fetus can suffer brain & other organ damage. It is not a risk to your eggs & is rather uncommon. Just having someone else change the kitty litter during a pregnancy will avoid the issue.
