You dream of a kitten and feel that you haven't eaten for several days, which means that you will be rewarded for helping others in real life.
In your dream, what the cat said to you may be that some kind fairy is holding a dream and educating you through a kitten. It means that you have wisdom roots and immortal bones, and you can cultivate immortals before you die, so you can fly to the celestial world after you die, but this statement is not credible. I hope you don't adopt.
This dream is normal, because what you thought during the day, or what you experienced before, you accidentally felt it. In this dream, you have this dream through the combination of reality, fantasy and dream.
