There is toxioplasmosis to consider, but I think it's rare. It's only transmitted through kitty poop, that's why they say pregnant women shouldn't handle litter or where gloves when chnging litter. As far as the cats being harmful to the baby, that's a load of bull. As with any animal be it a cat, dog, ferret etc.., if you don't watch them together, of course something harmful could happen...But, supervision is the key if you're going to introduce your pet to your baby. Cats are no more dangerous to a baby than any other pet you have in your house. Good Luck! Hope to hear good news soon And hey, this is a good time for hubby to start changing the litter all the time because you could *possibly* be pregnant...and then when you know for sure, he has no choice but to have to change it! Ahhh, can you just imagine 9 months of not having to change litter?! oh, to dream
