4. Aggressive cat behavior between cats and each other
The most obvious and easily understood type of cat aggression occurs between unneutered males. When males reach adulthood, they often begin to challenge each other for access to females or territory. Male cats that roam will get into serious confrontations and real fights.
They will sit or stand stiffly, staring at each other.Their ears are turned back, and they often hiss and howl loudly.One of the cats may eventually leave slowly, or one or both cats may attack.
5 -Aggressive cat behavior may be related to private ownership
Animals of many species seek to drive other individuals out or drive them off their territory, and cats are no exception.
Both male and female cats are territorial, but males may defend larger territories than females.
Cat territory aggression is usually directed at other cats, but it can be directed at dogs and people as well. A cat can show territorial aggression toward some family members but not others and toward some cats but not others.
