How to Stop Your Cat From Rejecting a New Kitten

Some cats take to new kittens right away. Others need a lot of time to get used to a new kitty or may never fully adjust. A lot of this depends on how old and well socialized your cat is when it's introduced to your new family member.

Although cat behavior may be difficult to understand at times, looking to their wild relatives can offer some insight as to why cats sometimes have trouble coexisting.

Why Do Cats Reject New Kittens?

Domesticated house cats are closely related to wild cats. There are a number of differences, but these groups still have some similar characteristics and instincts, including how they coexist with other cats.

Wild felines, such as bobcats, lynx, and servals, are typically solitary animals. They're rarely seen, naturally secretive, and nocturnal. During the day, they hide in dens, and they come out at night to hunt for food alone.

Feral cats (domesticated cats that have grown up in the wild) also hunt and sleep alone. However, they may form a colony led by a female cat (queen) if food is being provided to them by people. Colonies are generally made up of related cats. Male cats (toms) usually leave the colony when they are a few years old.

This social hierarchy is different from that of the average house cat. That's because house cats are usually spayed and neutered, often not well socialized with other cats, and live in a very isolated environment away from other cats. This can present a problem when you want to bring a new kitten or cat into the family. In addition, feral cats usually live in colonies of genetically related cats that are born into the colony. It is uncommon for unrelated cats to join their ranks, and when they do, they usually live on the outskirts of the colony for several months before they are fully accepted.

Sometimes, giving your cat time to adjust to a new kitten is what's needed. But if your cat was not well socialized before the age of 3, it may be very difficult for it to get along with a new kitten. In reality, some cats are better off being the only cat in a home.

How to Stop Rejection

When you bring a new kitten home, it's important to slowly introduce it to your cat. Whether you've done that or not, if the cats aren't getting along, there are a few steps you can take to try to break the ice.

Food Bowls

Make sure the kitten has its own food and water bowls that are not in the same location as your cat's bowls. Feed them in separate areas so your cat doesn't become territorial about its own food and your kitten gets a chance to eat. If you need to, feed one of the cats in a separate room and close the door.

Sleeping Areas

Provide separate sleeping areas for both cats. Don't try to give your cat's old beds or condos to the new kitten. Your older cat has already established possession of these and won't take kindly to a kitten using them without permission.

Observation Areas

Cats usually deal with "intruders" by trying to avoid them, and only display overt aggression as a last resort. Your cat should have a safe place to get away from the new kitten until they have gotten comfortable with each other. Provide your older cat with areas outside the kitten's reach where only it can go. A high perch, for instance, can be a good place for your cat to observe the kitten for a while. Also, these places can be a good retreat when your cat needs to get away from an aggressive or annoying kitten.

Litter Boxes

Make sure you have one more litter box than you have cats. This means that if you have two cats, you should have three litter boxes. There should be no direct line of sight between the boxes in case both your older cat and new kitten are in different boxes at the same time.

Pheromones

Purchase sprays, wipes, and diffusers containing special feline pheromones and use them as long as necessary. These pheromones help cats feel relaxed and safe and may benefit both your new kitten and older cat during the introduction phase.

Treats

Pet your new kitten and, at the same time, allow your older cat to sniff you while you give it its favorite treats. This may help to teach your cat that the scent of the new kitten is not a bad thing. Over time, your older cat may start to associate the smell of the kitten with treats, making it a positive scent. Do the same thing when you see your kitten and cat interacting nicely to reinforce their desirable behavior. 

Separation

Cats should not be allowed to be together unsupervised until they have had several direct interactions without any issues. If you're unable to monitor your cat and kitten and are worried about one hurting the other, make sure they're safely separated. A bathroom with a litter box, bed, and bowl of water can be where the new kitten stays when you're away at work or asleep at night. This is especially helpful if your kitten won't leave your older cat alone.

Keep Things Calm

Sometimes unusual things that scare a cat will cause it to show displaced aggression toward a new kitten. Cats are creatures of habit, so don’t make major household changes while introducing the new kitten. This includes such changes as renovating your kitchen, ripping up carpeting, or having a party with fireworks in the backyard.

Don’t Allow Fights

While they may want to fight, don't allow your cat to do anything more than hiss and swat at the kitten. If you're concerned that a fight is about to happen, distract the cats with a loud clap of your hands or a quick squirt of water. If your cats do fight, they should be separated for a period of time, and then slowly reintroduced to each other over a period of several days to weeks.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
