Certain animals carry disease that could be detrimental to the health of your pregnancy.
Cats carry a bacteria called toxoplasmosis. If you contract it during your first trimester, it can cause some anomalies in the development of the fetus. During your entire pregnancy, avoid changing your cat’s litter. Ask another member of the family to do so. Also, wash your hands frequently after being in contact with your pet and before eating.
Rodents (mice, hamsters, guinea pigs) can carry a parasite called leptospirosis that can also affect the development of your fetus. Avoid changing the cage of these animals and avoid petting them as they are more likely to bite. Reptiles (lizards, turtles) can carry bacteria called salmonella that can greatly affect you and your baby's health.
