Floofdar (catfinition) – a cat or dog’s ability to detect another animal’s presence that evades human awareness.
In use: “Something apparently triggered Flash’s floofdar, for awakening and rising, she trotted to the window sill and peered out. Whatever she saw prompted her to issue a low warning growl. Nan, watching and listening, said, “How did you know something was there? You were dead asleep.” She got up to see what triggered her cat’s floofdar.”
