I like the screen door idea but we live in a rental so can't do that. I think we will either shut the baby's door or lock the cats in the laundry overnight.

I'm 22 weeks and the other day while sleeping on me, one of my cats got kicked by bubs so hard that he woke up and jumped! Also occasionally now when my cats see my belly move, they try to pounce on it...I don't let them do that though.
