Tension between cats

Are your cats not getting along well or are they fighting?

Tension between cats is a very stressful situation in your household, both for you as an owner and for your cats.

It's important to know that cats are not social animals by nature; they are solitary hunters. This doesn't mean they are completely solitary, but rather that they prefer to do everything alone: eating, hunting, sleeping, going out, scent marking, using the litter box, etc. We prefer to describe the social behaviour of our cats as: solitary by necessity, social by opportunity.

If your cats are fighting, separate them immediately and seek help. Cats do not have reconciliation behaviour; they cannot say sorry, and every conflict makes their negative association with each other worse and worse. So, there is no such thing as 'Let them fight it out' – that is the worst advice ever!

Also, please never just put two cats together. In the wild, cats are enemies, equipped with sharp teeth and claws that can inflict fatal wounds. That's why a cat won't just fight; its first instinct will always be to try and hide or flee. By the time cats resort to fighting, they have already passed several levels of the 'cat game' and are forced to resolve their tensions through conflict, usually because they cannot get away from each other.

If we look at wild colonies that form naturally in the wild, they look very different from how we keep cats together. They are colonies consisting of female cats who are related to each other, not spayed, who den together for the common care of the kittens. Occasionally, a male cat may be part of the group, but that does not mean he is the father of the kittens. The condition for the formation and maintenance of these natural wild colonies is the presence of sufficient feeding locations and sufficient shelters.

So, if you have several spayed/neutered cats in your home that are not related, a mix of males and females, and they are simply put together, the chance of tension and aggression is very high.

But don't worry, we are here to help you turn over a new leaf and improve and relieve the tension!
