There are many reasons to add a second cat to the house, including giving a home to another homeless cat, providing a latchkey cat with feline company, and “why stop at one, when two are more fun?”
How do you introduce New Cat to Resident Cat and vice versa?
“Tabatha, meet Tony, the resident cat. Tony, meet Tabatha, your new feline housemate. I’ll leave you two alone so you can get to know one another.”
If only it were that simple.
One of the keys to a mutually satisfying multi-cat household is making sure that your current cat and your new cat start off on the right paw. This requires some knowledge, forethought, and finesse on your part. Though each cat is unique, fortunately there are a number of cat introduction techniques that work on most cats, most of the time. Here are the main steps to ensuring a low-stress transition and lots of happy purrs.
Phase 1: Select a Cat Who’s Compatible with Your Current Cat (Unless the Cat Selects You)
Whenever possible, a high-energy kitten or young cat should be paired up with another high-energy kitten or young cat, so each has a compatible feline playmate. In general, try to match New Cat to Resident Cat. For example, if Resident Cat is older and stately, he may not appreciate a rambunctious kitten. Granted, sometimes New Cat is a stray who finds you rather than the other way around, so you just have to do the best you can.
Phase 2: Prepare for the New Arrival
The following proactive tasks will help the transition to a multi-cat household go more smoothly:
Territory, from a feline perspective, is not just space (horizontal and vertical), but access to prime resources. Prime resources are objects or aspects of life that cats desire strongly on a day-to-day basis. They include:
If the cats, respectively, will let you, trim their claws before their first meeting, and periodically as the meetings progress—as extra insurance against injuries to them or you.
Territory disputes are a common source of friction between cats. Ensuring that the cats feel confident about their access to territory goes a long way toward maintaining peace and harmony.
Phase 3: The Debut of Cat Number Two
The “Welcome Home” Suite and Introducing the Cats to Each Others’ Scents
When the big day arrives, and you show New Cat her new lifetime home, place New Cat in her well-appointed quarantine quarters. Open her carrier and let her walk out at her own pace. Give her time to adjust to her private space. Resident Cat will know something’s up, but at least initially he won’t have to directly contend with a competitor during daily routines.
Cat scratches and bites can do serious damage. Bites especially can lead to dangerous infections; seek prompt medical attention if you are bitten by a cat.
Let each cat sniff the other’s scent. Rub a cloth or sock on New Cat and take it to Resident Cat so he can investigate it with his discerning nose. Give Resident Cat a favorite treat and/or indulge him in activities he likes, such as playing or brushing, to help him make positive associations with New Cat’s scent. Then perform this sequence in the other direction – rub a cloth or sock on Resident Cat, take it to New Cat, and so forth.
After a day or two, and possibly with some human volunteers to help you, have the cats switch places for a little while. Resident Cat can thoroughly check out New Cat’s temporary room, and New Cat can have the run of the house. Both cats will take in loads of information from sniffing, and leave their scents in every spot that’s strategic from a feline point of view.
Stress-busters such as interactive playing, ample scratching opportunities, catnip (for cats who enjoy it), and luxurious petting sessions may significantly help both cats adjust to their new living situation.
Phase 4: Managing “Getting to Know You” Visits Between Resident Cat and New Cat
At some point the cats will be ready to meet face-to-face—and that will kick off the next-to-last phase of the introduction process: a series of cat-to-cat meetings that let the two cats become comfortable with being in the same place at the same time.
Use your best judgment on when to have the initial meeting. Every cat-to-cat relationship proceeds at a different pace. If both cats seem to be more or less settled and doing normal cat activities, perhaps they’re ready to see, not just smell each other. With two kittens, this could be an hour or two after New Cat’s arrival. With two curmudgeonly cats who are set in their ways, you might have to wait a couple of weeks or more.
There are several well-tested variations on how you can set up and direct this series of meet-ups. But first, here are the basic guidelines that apply to all the techniques:
Here are some of the most favored techniques for allowing the cats to get acquainted:
Let each meeting continue as long as the cats are being civil to one another. Tolerate growling and posturing, but if they start to fight, or if one of the cats is clearly traumatized, end the visit. It‘s better to have fifty brief visits that go well than to have one extended visit that ends in injuries and a trip to the vet.
There’s no upper limit on the amount of brief meetings to have before the cats are free to roam the house unsupervised. With two kittens, the whole process could be over in less than a day. Two stubborn adult alpha cats may need several weeks of limited face time before they’re ready to be left alone in the same room.
Phase 5: Settling Into One Big Happy Family
When the cats are generally going about their business in the presence of each other and seem to have reconciled that they have a permanent feline housemate, you can ease up on the supervision. Let New Cat have access to the entire house—at least the part where cats are allowed. Keep an eye on things.
Double-check that the cats have sufficient territory. Rearrange the layout if necessary, to help foster peace and minimize inter-cat bickering.
The Welcome Home room should stay in place for a while, until New Cat doesn’t use it as a refuge.
Considering that cats in the wild are primarily loners, it’s amazing how well most of them adapt to living with feline company under the same roof. In many cases, the cats become best buddies—playing, sneaking around, and snoozing together. While tempers may flare during the introduction period, once that settles down, usually everyone can relax and enjoy the start of new, beautiful friendships.
