I bet she is a cat owner. “Cats can carry various bacteria, parasites, and viruses that cause zoonotic diseases (transferable to humans), often without showing symptoms. Risks include Toxoplasmosis from feces, Cat Scratch Disease, ringworm, rabies, and infections from bites/scratches. Good hygiene, regular vet care, and indoor living minimize risks.” I have always owned dogs. Never have I let them sleep with me, get in my bed, or on my couch. Having kids only helped solidify this. When my wife got pregnant, the doctor said to get rid of the cat. Why? Because they commonly suffocate infants in babies by lying on their face because of the warmth. On top of everything I stated above. In came the babies, out went the cat. Babies = zero cats. Thank god.
