We also raised cats with all our kids. No issues at all. As soon as we came home, we always laid the baby on a blanket on the floor and allowed the cat(s) to have a good smell. There were never, never, never, any issues at all. We were always careful doing this - just in case - but there just wasn't anything. Often after that, when we plopped the baby down on the floor on a blanket with toys, etc. the cats would lie down beside.
