Children younger than 5 years old, people with weakened immune systems, and people 65 years of age and older are more likely to get diseases spread between animals and people (also known as zoonotic diseases). Pregnant women are also at a higher risk for certain animal-related diseases. Before getting a new pet, keep the following in mind:

• Households with children younger than 5 years old should not have pet reptiles (turtles, lizards, snakes), amphibians (frogs, toads), or backyard poultry because of the risk of serious illness from harmful germs spread between these animals and young children.
• People with weakened immune systems should take extra precautions when choosing and handling pets. Talk to your veterinarian for help picking the best pet.
• Pregnant women should avoid adopting a new cat or handling stray cats, especially kittens. Cats can carry a parasite that causes toxoplasmosis—a disease that can cause birth defects. If you are pregnant, you do not need to give up your current cat, but you should avoid handling cat litter.
• Pregnant women should avoid contact with pet rodents to prevent exposure to lymphocytic choriomeningitis virus, which can cause birth defects. If you're pregnant and have a pet rodent, avoid direct contact and have someone else clean its habitat.
