If you observe the behavior of cats in their natural habitat, you will notice that they can often bite each other in the neck area.
The same behavior can be observed if you have several pets.
Some owners believe that this is a demonstration of aggression and immediately try to separate the pets. But this does not always mean that the "victim" should be saved and the "aggressor" punished.
If cats are playing with each other, they may bite their relatives in the neck area. This behavior is quite typical for street and mongrel animals.
Their instincts are highly developed, so this "ritual" is a kind of training of hunting skills. In this case, the cats do not harm each other.
A bite to the neck area from a dominant individual can be a "confirmation" of its dominant position, experts note.
Quieter and calmer cats will be indifferent to the "ambitions" of their fellow cat.
Sometimes cats can actually be a bit aggressive in their behavior because they feel they are forced to "compete" for food, territory, and the owner's attention.
If the owner provides each cat with everything they need, they will stop fighting with each other.
