Laura: My Bryan also had his Harvey kitty who stayed with him all the time. Even in the crib! He would lay near but never quite touching Bryan. (this is Christine's husband and Misha's daddy) My mom was ballistic and one who told me the cat would "suck out the baby's breath". Of course, we watched carefully at first but learned that each baby was quite safe with our kitties. The others would just watch from afar. Missy had her Ernie all of her life - he died just a few days before her wedding. Thankfully, all of my children are pet lovers and so I know that my grandchildren will be as well.
Getting rid of a cat because of pregnancy is sheer ignorance. Now, if the infant were to have severe allergies - then rehoming would probably have to be done - but that is another story. Pregnancy is just a pathetic excuse to treat a pet as something disposable.
