OMG! Best Funny Baby ever! with cat.....

If there are going to be off-limits rooms once the baby comes, you'll need to start training your cat to be extra happy in places they can be. A cat tower, scratching posts, catnip toys, and other things your cat enjoys should be added to those rooms. Praise and rewards should be given when the cat is hanging out in them. Honestly, deterring a cat from a room or place in your house seems almost impossible without the cat turning on you or adding to their stress.

Noise is to be expected when bringing home a baby, so prepare your cat accordingly by recordings of baby sounds (not just crying). Be sure the volume isn't so high that you give your kitty anxiety before the baby even arrives. During the recordings praise and reward your cat for staying calm. Noise will likely be one of the worst stressors, so this step is very important.
