Are You Considering Getting One or Two More Cats So Your Current Cat Has Company?

If so, you’re probably wondering whether it’s even a good idea to introduce more cats—and if so, how to do it.

Fortunately, cats are generally social animals. This means that it’s often a great idea to have more than one cat—and ideally, to get multiple cats at the same time.

Even if you’re worried that your current cat may react badly, you can rest assured that, over time, the two cats are very likely to enjoy each other’s company.

That said, it can be helpful to choose a cat with a personality similar to your existing cat. This increases the chances that they’ll get along well.

How Do You Introduce Cats to Each Other?

First and foremost, it’s worth considering getting two cats from the very beginning, even when you’re getting your first cat. If you didn’t have the chance to do that and are now thinking about adding a second cat, don’t worry—it’s not too late. As mentioned earlier, cats are social animals, and their social needs aren’t always fulfilled by human interaction alone. Your current cat will likely be happy to gain a new companion.

When choosing the right second cat, try to find one that matches your current cat’s temperament. That gives the best chance of a harmonious relationship. As for gender, it usually doesn’t matter much when it comes to compatibility. The choice is up to you. If you want to avoid future kittens, it’s a good idea to neuter one of the cats. Neutering can also help with litter box habits and create a calmer temperament.

Benefits of getting a second cat:

  • Cats are social creatures—they thrive in the company of other cats
  • If your cat doesn’t have outdoor access, a second cat is especially helpful
  • With two cats, you no longer need to worry about your current cat being lonely when left home alone

Already Have One Cat – Can You Add One or Two More?

As with any pet, it’s important to think things through before making a decision. If you already have a cat who’s been living alone for years, there’s a chance they won’t accept a newcomer right away. They’re used to being the only one.

So if your cat is older, it may take patience and time before it warms up to the new family member.

If your cat is still young, it’s usually easier for them to adapt to a new companion. You might still find that the original cat insists on being the center of attention—but with time and a gentle approach, they’ll most likely come around.

Patience is the key word here. Give it time.

How to Do It: Step-by-Step

To ensure a smooth introduction, there are a few simple steps you can follow.

Start by not rushing the first meeting. Prepare a separate room for the new cat with its own litter box, food, and water. This helps avoid overwhelming your current cat and gives the newcomer a sense of security.

A separate room gives the new cat a safe and defined space from the very beginning. After all, adapting to a new home—and a new roommate—can be just as stressful for the new cat.

At the same time, it’s important to maintain routines for your original cat. Stick to feeding schedules, playtime, and keep their favorite spots unchanged. Also make sure the original cat still gets the most attention, so they don’t feel replaced.

This approach will help both cats feel safe and secure—and more likely to accept each other over time.

Help from Pheromones

If your cats are still struggling to get along, you can use artificial pheromones to help the process. These pheromones are similar to the ones cats produce naturally and can be used to reduce stress and promote calm behavior.

They’re available as sprays or plug-in diffusers that release pheromones gradually into the room.

Pheromones can help cats feel more relaxed around each other and ease tension in the home. They may also reduce problem behaviors such as indoor spraying or furniture scratching.
