If you have a stubborn cat that won’t stop climbing into the baby’s crib or sitting on the kitchen table, you have to make it so that they won’t want to do so anymore. Cover the surface in some aluminum foil, and you’ll find that your cat quite detests the sound when it jumps on top of it. If you put some masking tape down with the sticky side up, it’ll stick to your cat’s feet as they walk all over it, which will help them learn to avoid it.
