This guide provides advice for introducing a new cat into a home with existing pets or babies. It recommends confining the new cat to a single room for the first week to allow it to adjust. When introducing cats, keep them separated for at least a week and let them get used to each other's scents before any direct contact. Introducing cats to dogs requires leashing the dog initially and supervising all interactions. Babies and cats also require supervision, and the cat should be conditioned to gentle touching. Patience is needed for all introductions.
