A new home can seem huge, intimidating and overwhelming. So find a room that will allow the cat to get accustomed to the smells and sounds. Placing a cat-calming Feliway plug-in device in the room may also help.

If you have other cats or pets, a several-step introduction is best. First, allow your current pets to see the new cat through a baby-gated doorway or by someone holding the new cat while your current pet is held and petted (to reduce anxiety and jealousy.) Cats will invariably growl and hiss during introductions. Keep petting and talking to all pets. Let the pets decide when they want to get closer to sniff each other, which may take days or even weeks.

If this is your first cat, be sure electrical cords are hidden or secured to avoid chewing; check tables and shelves for breakable items; beware of lit candles on low tables; and be sure basements and other areas don’t have small openings to the outdoors. Lock away cleaners, chemicals, fertilizers and other toxins with baby-proof hinges. Have at least one litter box per cat.

During the first weeks of allowing your new cat to roam free in your house, it's best to be watchful. You can help it locate litter boxes and food/water bowls and you'll discover its hiding places. And if you have other pets, you can ensure there are no conflicts.

Keep your level of attention for existing pets consistent when a new cat arrives. If you suddenly stop or reduce the level of play and interaction with current pets, jealousy can ensue and the new cat could become the target of attacks. Engage in playtime with all the cats together.
