Cats know they are loved by their owners. Although cats don't express their affection as openly as dogs, they can sense their owners' love through their actions and tone of voice. For example, when owners gently stroke their cats, play with them, and provide them with food and a comfortable environment, the cats can feel their love and care.

In addition, cats can also judge their owners' emotions by their facial expressions and voice. When owners smile at their cats and communicate with them in a gentle tone, the cats feel safe and relaxed, thus becoming more trusting and dependent on their owners.
