If you love sharing your home with a cat, it's hard to resist adding even more feline friends to the family. However, you should keep in mind that your cat might not feel the same way.

Cats are social creatures, but not everyone gets along. It is not uncommon for cats to aggressively resist socialization with other cats. Even cats that love people and get along well with dogs, birds, rodents, and other animals may not like another cat in the family.

If your cat doesn't get along with other cats, it could be disappointing. However, it helps to understand why your cat feels this way. With a little more insider knowledge, you can be more empathetic to your feelings and there's even a chance you'll change your mind.

1. Lack of socialization

The most common reason an adult cat grows up not to get along with other cats is because vital socialization was lost during childhood.

The most common reason an adult cat grows up not to get along with other cats is because vital socialization was lost during childhood. All kittens go through a phase where they are most receptive to new experiences.

This occurs in most kittens between 2 and 7 weeks of age, and can sometimes extend to around 14 weeks of age. During this important window, the developing brain forms more lasting associations and bonds.

This means that the lessons kittens learn and experiences they encounter will stay with them well into adulthood. For example, a kitten who spends those vital weeks enjoying time with people, dogs, and other cats will likely grow to continue to enjoy these experiences.

When it comes to other cats, a kitten that grows up with her littermates and spends time with other cats has a good chance of being friendly with other cats as an adult. Many cats who hate other cats were separated from their siblings at an early age.

Without initial positive associations to build upon, the cat may become resistant to these new experiences after this socialization window closes. Fear of the unknown is a powerful influence.

We must also remember that socialization goes both ways. The keyword in the scenario above is "positive". Even if a kitten grows up with other cats, if the overall experience is negative or if they experience something traumatic like being attacked by another cat, that memory will stay with them and could affect their behavior in the future.

An adult cat can form new associations and improve its social skills. However, it is usually more difficult and may require more time and patience.

2. Protection of your routine

Changing an established routine in any way can cause a negative reaction from a sensitive cat.

Your cat might randomly jump up and run down the hall or attack your ankles out of nowhere, but cats are generally not spontaneous creatures. They like predictability and routine. A fixed schedule helps them feel more secure and in control of their circumstances. Changing an established routine in any way can cause a negative reaction from a sensitive cat.

There are few events more upsetting than having a stranger barge into your life. For your cat, the arrival of a new pet in the home will disrupt any routine they have come to enjoy. How and when they are fed, how much attention they are given, and even the freedom to nap wherever they want: a new cat changes everything.

There are certainly some cats that can accept change and move on. However, others find it too distressing. If your cat seems to hate other cats, he may just hate that his routine and comfort are compromised by a new arrival.

3. Protection of your territory and resources

Why does my cat hate other cats? (4)

In addition to routine, cats value their territory. As territorial creatures, cats typically spend their entire lives within what they believe to be their geographic boundaries. Even feral cats rarely venture too far from what they consider to be their home territory. Cats can share territories. However, many will resist any cat (and sometimes humans or other animals) that try to enter.

Territory is especially important for cats that are not spayed or neutered. In many cases, it is simply impossible for two intact (unneutered) male cats to share close quarters. The same can also be applied to intact females. Their hormones prevent them from living in peace.

In addition to the physical area, cats can also be socially territorial. This means they become possessive of the people they care about. It's unclear whether cats can feel genuine jealousy, but their territorial feelings towards a favorite human can lead to significant arguments when another cat enters the home.

Cats have similar feelings about food and water. Dividing a territory means sharing these vital resources. Of course you make sure all your pets have everything they need. Adding another cat doesn't mean the first cat gets less food, but a worried cat might not be convinced.
