Cats display a variety of protective behaviors that help ensure the safety and comfort of their human families and their homes. They mark their territory by rubbing against people and objects, keeping a vigilant watch from windows, and bringing gifts like mice or birds, which is their way of providing. Cats also sleep with their owners to protect them at night, hide objects, interrupt other pets to maintain peace, and even alert their owners to strangers. Their behaviors extend to detecting illness, purring for healing, and maintaining high vantage points to survey any threats. Additionally, cats can sense environmental changes such as weather shifts or household dangers like gas leaks, acting as both companions and protectors in subtle yet profound ways.
