Cats typically express their affection and trust towards humans through purring, rubbing, and nuzzling. In return, humans respond to this emotional connection by petting, playing, and taking care of their basic needs, such as food, clean drinking water, and a safe habitat.

Scientific research has also shown that interactions with pets like cats can have positive effects on a person's physical and mental health. For instance, they can help lower blood pressure, reduce the risk of heart attacks, and improve mental health levels.
