This is particularly true of tightly bonded cats that depend on their owners for lots of physical contact and play. If you plan ahead, you can make the arrival of a new baby much less stressful - at least from your cat's point of view. The first step is to introduce the cat to the baby's things. Curiosity specialists that they are, cats will usually investigate the new crib, toys, blankets, and other paraphernalia without much prompting. But if you plan to do a lot of nursery redecorating, do it gradually over several weeks.
Many cats become uneasy with mass migrations of furniture.
Your cat will also benefit from a slow introduction to the sight, sounds, and smells of a baby. If you have any friends with babies, invite their little ones over to meet your cat. Also, consider getting a recording of a crying baby. Play it at irregular intervals. Expose your cat to baby product smells by putting infant lotions and powders on you hands every day for several weeks before the baby's due date.
