How to Reduce Fighting Among Cats in Multi-Cat Households

How to Reduce Fighting Among Cats in Multi-Cat Households

            Cats are great companions and about 44% of households with cats own 2 or more cats.  However, cats don’t always enjoy the company of other cats. The more cats in a home, the more likely there will be some stress and dissent among the ranks.  So, what can you do to keep the peace among a clowder of cats?  Let’s find out!

• Make sure you have enough resources to go around.  Cats can be territorial and possessive.  If they feel they don’t have enough food, space, places to go to the bathroom, etc. cats will become stressed and may be aggressive towards each other. The more things they don’t have to share, the better.  Have one to two more litter pans than the number of cats in your house, make sure they are cleaned daily and in various areas if possible.  Have vertical space and hiding spots available with one or more cat trees or similar areas to allow cats to have some “me time” when they need it.  Have multiple food and water bowls so cats don’t feel stressed around meal time. Many cats also prefer to eat alone, so feeding cats in separate areas or at least feeding each cat in his or her own bowl may eliminate stress and competition around meal time.
• Make sure cats have plenty of interactive play time with their humans and that they have environmental enrichment and mental stimulation.  Offer a variety of toys and rotate them to prevent boredom. Have one-on-one play sessions if needed to reduce the chance of one cat keeping a toy all to himself.  A tired cat is a happy cat—keeping cats active and engaged means they are less likely to be discontent which reduces fighting and keeps cat mentally fit.
• Reward good behavior! If your cats are all in the same room and everyone is chill, give them all a few treats or a good chin scratch to reinforce calm behavior.  Pheromone products such as Feliway can also have a general calming effect on cats.  Diffusers allow these calming chemical signals to infuse the air—most are derived from cheek gland secretions which promote a calm, positive vibe among cats.

Cats fighting?  Here are some DON’TS:

            Don’t put yourself in the middle of fighting cats.  DO try to distract them and break up the fight, but do it safely! If you try to physically grab your cats, they will likely bite and scratch YOU causing serious injury.  Try making a loud noise, tossing a pillow or blanket at them or using some other distraction to break them up. Don’t risk bodily harm to stop a cat fight.

            Don’t punish you cat.  Yelling at, hitting, or otherwise punishing cats for bad behavior may actually make the situation worse escalating fear or aggression. It’s tough to reign it in when emotions run high, but try to remain calm if cats are fighting.

            Don’t reassure them.  On the opposite end of not punishing your cat, you also don’t want to try to calm cats after a fight.  Interacting with cats that are on high alert after a fight could not only inadvertently reinforce the behavior, but it could lead to more aggressive behavior towards you.  Just separate the cats and give them some space. Don’t try to coddle cats after a fight.

An occasional hiss or chase through the house is normal and not too concerning. And, remember, introducing a new cat to a household will take some time for everyone to adjust. If your cats are frequently fighting, contact your veterinarian or a veterinary behaviorist for help. Cats can become ill if under chronic stress and they can also sustain injuries or develop secondary behavior issues such as urinating outside the litter pan.  Cats who are constantly fighting are not happy and they may require medications and methods to re-train them to at least tolerate their house mates.  Don’t let cats “fight it out.” Get help!
