Can a cat get Territorial over master?

While cats can absolutely be territorial, they usually direct their territorial behavior towards places, objects, and other animals. It's very unlikely that a cat would become territorial over its owner in the sense of trying to prevent them from interacting with others.

Here's why:

* Cats see humans as caretakers: They don't view us as equals in the same way they might view other cats. We provide them with food, shelter, and attention, so they generally don't see us as rivals for resources.

* They don't understand "ownership" the way we do: Cats don't have the same concept of ownership as humans. They might mark their territory with scent, but they don't typically feel possessive of their humans in the same way they might feel possessive of a favorite toy or spot on the couch.

However, there are some situations where a cat's behavior might *appear* territorial towards their owner, but it's usually due to other factors:

* Stress and anxiety: A stressed or anxious cat might become more clingy or demanding of attention, which could be misconstrued as territorial behavior. This is more likely if the cat is experiencing changes in its environment or routine.

* Medical issues: Certain medical conditions can cause changes in a cat's behavior, including aggression. If you notice a sudden change in your cat's behavior, it's important to consult a veterinarian.

* Lack of socialization: Cats that haven't been properly socialized as kittens might be more prone to displaying fearful or aggressive behavior, which could appear territorial.

In summary: It's highly unlikely that a cat would become territorial over its owner in the traditional sense. However, if you are concerned about your cat's behavior, it's best to consult with a veterinarian or certified animal behaviorist to rule out any underlying medical or behavioral issues.
