A dominant cat is an assertive cat that controls the territory, staying defensive and protecting turf. No “alpha feline” or “boss cat” is in charge of everything- that’s not what happens in the wild.
A cat shows submission to another cat by the way they position their body, including their ears and tail, and mighteven flatten their ears to appear smaller.
Being dominant doesn’t always mean that your cat is acting aggressively. It’s important to consider if either of them is being harmed by the interaction.
