OP, have you been around cats all your life? My OB said it was fine for me to do litter (hubby was deployed) with gloves. I had been around cats all my life though, so the disease (can’t remember) I most likely was immune to or already had. As far as cats being dangerous- what? Some believe that a cat will suck the life out of a baby, is this your MIL’s superstitious way of thinking? Cats love warm spots, and babies are warm, so they will lay near a baby, and you have to watch them, but usually they stay away, especially if you shoo them away enough. I never had a problem. But no, you shouldn’t have to pick, that is not a fair ask. Fiancé sounds like he has cold feet. Call him on it and ask if he is having second thoughts about having a family. I mean, 19 is super young. No matter, he has responsibilities, and he has to help with this baby financially if not physically. But if he is going to be a child, then it is best he not stick around so that you are raising two babies.
