Help! My cats are fighting seriously. How do I stop the aggression?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 1 year and 6 months old | 6.5 lbs

Hi. My cat is being agressive towards my other cat. I can't leave them in the same room. And I don't even know how to seperate them in different rooms. We had living room and kitchen room but without doors that I can stop them from seeing each other. They are seriously injured after fighting. I can't leave them every second. If my cat going outside, they will fight. If my other cat going inside, they also going to fight. What should I do to them???

Getting them fixed would be the best start as this will take away the hormones. From there you can try pheromones such as Feliway spray to help keep them calm. I am unsure if the dynamics but maybe one is more outdoor, the other more indoor to help keep them separate. Make sure there is no competition such as food or water.
