Singing is often associated with feelings of happiness and joy, and a cat may be drawn to a person who is singing as a way of seeking out positive emotions. Cats are social animals and may be attracted to the social interactions that singing can provide.

It is also possible that a cat may be responding to the tone and inflection of the singing voice, as cats are able to detect and respond to changes in vocal patterns and tone. The singing voice may provide a source of comfort and security for the cat, particularly if the cat has a close bond with the person who is singing.
