Aggression Between Cats: How To Manage Cat Resources Within Your Home
Cats in general prefer not to fight. Instead they use visual and audible communication to avoid physical confrontations and adapt to living in a group though the development of social structures. Sharing a home can be difficult for cats and can result in stress-related behaviors (such as urine marking) and/or inter-cat aggression.
Physical restrictions on space and limited options for avoiding each other when living in our homes can mean that the location and availability of resources is key. Ensuring each cat has access to food and water bowls, litter boxes and exit/entry points to the home without having to interact with each other, helps each cat cope with living close to others.
Cats can display aggression subtly such as blocking each other, staring, spending most of the time up high or hiding, changes in food consumption, grooming changes or stress-related behaviors, as well as physical interactions. Aggression can often be seen in cats newly introduced to each other or between cats that have previously been friendly however an event has resulted in aggression. These events can include a change in the home (such as renovation) or when a cat returns from time away (such as at the vets). Aggression can also result from a cat being in pain or if it has an underlying medical problem, so in cases of inter-cat aggression it is advisable for cats to be examined by their vet. In addition, when a new cat is brought home and introduced to a resident cat, aggression can be due to territorial and/or fear related issues.
Now there is an extra tool available for owners who have cats that display aggression in the home. The cat appeasing pheromone is released by a queen when she is nursing her kittens to encourage a feeling of safety for them and also a bond between them. A synthetic copy of this pheromone (FELIWAY® Optimum) is available as a diffuser which should be plugged in the area where cats spend most of their time (usually where they sleep) and has been shown to reduce signs of aggression between resident cats.*
Knowing where to position resources can be difficult. FELIWAY® has produced a fun tool to help you learn more about this.
