* Testosterone: Male cats have higher levels of testosterone, which is a hormone associated with aggression.
* Territoriality: Male cats are more territorial than females and will fight to defend their territory. This is especially true during mating season when they are competing for mates.
* Socialization: Male cats are often raised in separate litters from their siblings, which can lead to them being less socialized and more prone to aggression.
However, it's important to note that individual personalities and experiences play a significant role in a cat's tendency to fight. There are plenty of female cats who are aggressive, and many male cats who are perfectly peaceful.
Overall, male cats are statistically more likely to fight, but individual factors can make a big difference.
