Floofsayer (floofinition) – someone who can predict a cat or dog’s behavior.
In use: “I met a man who claimed he was a floofsayer. He gave me a kitten and said, “This cat will love you more than any person or animal has ever loved you. She will follow you everywhere, including the bathroom, and sleep on your pillow against your head.” He was right in all regards. That kitten is now ten years old, weighs twenty pounds, and still sleeps on my pillow against my head.”
