The human version of Enneagram personality type 8 is popularly called the challenger, the protector, or the powerful person. Typical characteristics focus on being strong and not vulnerable, taking charge and in control, being direct in going after what's wanted.
The cat version of Enneagram type 8 we call the Territorial Intimidator or the Boss Kitty. The Boss Kitty's attention is on maintaining control of their environment.
Dominance
The Boss Kitty may be asserting dominance due to territorial instincts, guarding of resources, and establishing a social hierarchy.
Ownership
Your cat may not only claim ownership of territory (certain areas inside the house or outside) but also resources (of which you may be one).
Control
This isn't self-control for your cat, but control of the domain they've claimed and all who live in it or venture into it.
Autonomy
It's your cat deciding what they will or won't do for themself, not subjected to the will of others (both people and other animals).
Respect
Respect means dominance isn't challenged. That respect may have to be earned and maintained through confrontation, intimidation, and vigilance.
While the Boss Kitty can be confident and resilient, there can be an assertive dominance that intimidates other pets in the household or neighborhood.
