Mewincholy

Mewincholy (floofinition) – a housecat’s sound of pensive sadness, often with no discernible cause.

In use: “Sitting in the living room, not far from him as he read his book, his cat released a a deep mewincholy, breaking his focus. “What is it?” he asked, staring at his fur friend. In response, she turned to him and unleashed a softer rendition of the same sound.”
