While you’re no doubt excited about bringing another animal into your home, your pets (both new and existing) might be less enthusiastic at first. Animals love predictability, and a new family member means that established territories, routines, and social dynamics are all about to shift. But with a little planning and a lot of patience, you can make the transition easier for everyone—including you.
Do a Pre-Intro Health Check
Before introducing a new animal, make sure all your pets, old and new, are healthy and up to date on their vaccinations. Ask your vet about parasite testing, and FIV and FeLV testing for cats. If your new pet has special dietary needs, this is a good time to start thinking about how you’ll fit them into your established pet care routines. Consider getting an RFID cat feeder or dog feeder that knows who to let in and who to keep out.
Create a Safe Retreat
Cats and dogs have different territorial instincts, but all animals need a safe place to retreat when life gets stressful. Before your new pet arrives, designate a quiet spot that’s just for them. This could be a spare room or a sectioned-off area. Equip it with their food, water, bedding, toys, and a litter box for cats. A pet camera is a smart way to keep an eye on them while they’re tucked away.
A dog might be ready to explore the rest of your home after a day or two, but a cat may not want to leave their retreat for a week or more. In the meantime, your existing pets are also getting used to their new family member's presence from a comfortable distance. Resist the temptation to hurry things along and let everyone go at their own pace.

Start with Scent Swapping
For pets, scent is everything. So before any direct introductions are made, let your pets get accustomed to each other's smells. After a day or so, swap bedding or toys between your pets, or gently rub a cloth on one pet and then the other. This safe, passive exchange lets everyone get used to the idea of another animal in the home. Swapping scents can even help them get to know each other a little—think of scent as a sort of animal résumé—without the stress of face-to-face interaction.
Relieve Stress with Routine
It’s normal for your existing pets to feel insecure and even a bit jealous. Reassure them that their place in the family hasn’t changed by sticking to their established routines. Give them their usual walks, play time, and one-on-one attention, and feed them at the usual times and in the usual spots. If maintaining a feeding schedule is a challenge, an automatic cat or dog feeder can make it easy to keep things on track. Your consistency will help them see the new pet as an addition, not a disruption.

Keep Intros Short and Sweet
When it's time for an official introduction, choose a location that’s controllable, predictable, and neutral. For dogs, leashes are generally recommended. For cats, a baby gate or carrier can provide a safe barrier. Keep the intro short and end things on a happy note with lots of treats and praise. You want all your pets to leave the interaction with positive associations.
Pay Attention Post-Intro
Once your pets are ready to cohabitate, it’s a good idea to supervise them as much as possible while they’re still getting to know each other. When you can’t be there in person, a smart pet camera can keep you connected and in the loop. Look for an indoor cat or dog camera with motion alerts so you can stay on top of things when your day gets busy and two-way audio that lets you talk to your pets remotely when they need a reassuring voice.
Bringing a new pet into your home is definitely cause for celebration, just take it slow. Use these strategies and smart pet care to ensure every family member, old and new, feels secure, happy, and loved at every step. You’ll not only help everyone avoid conflict, but create new family bonds that will last for many years to come.
