Unlike dog aggression , which basically occurs due to the inherent dominant nature of dogs, feline aggression is most of the times a playful activity. Cats seldom indulge in aggression without provocation. But they are likely to react aggressively if provoked too much. A fearful cat is more likely to try the escape route and hide behind a sofa. Biting is not a natural response that it has.

But it is not uncommon to hear about cats losing their homes due to aggressive behaviors like biting. Physical distress and fear are factors that can drive cats to indulge in biting in a manner that it provokes aggressive dog behavior .

However, it is only when aggression is encouraged or ignored that a cat tends to behave aggressively. A delivery man, who hides or runs away on seeing a household cat that shows aggressive body language, is sure to instill enough confidence even in an otherwise docile cat. He will remember it and every time a delivery man comes knocking he is liable to face an increasingly aggressive cat every time.
