1. Two male cats may fight together. If two cats who don't know each other suddenly get together and behave in a territorially offensive manner, they will most likely fight. But if there are two cats that have been raised since childhood and are often together, they may not fight, but just play and play.

2. In order to strengthen the relationship between the two cats, you can try the following methods: First, put the subsequent cat in a cage and place it in a place where aboriginal cats can often see it, so that they can get familiar with each other's taste first. Secondly, after both parties get used to each other, they can be let out to play together. It is best to prepare 2 to 3 food bowls and 2 drinking bowls. The last step is to prepare the cat litter box. If there are two male cats, it is best to prepare three cat litter boxes to avoid fighting over the cat litter box and causing one party to stress to hold back urine and cause cystitis. If you want to raise two cats at home, it is recommended to start with kittens to better cultivate the relationship.
